try calling objRunspace.Close() explicitly.
Since both PowerShell and Runspace implement IDisposable you can use 'using' block
using (var powershell = PowerShell.Create()){
...
using (var objRunspace = RunspaceFactory.CreateRunspace()){
...

}
}
Then you don't have to worry about calling .Dispose() it'll be called automatically when execution exit using block.

OK, 'never' is maybe too strong.
But you never know when will Designer decide to re-gen the file and overwrite manual changes.

What exception is thrown?

sjelen 25-Oct-13 10:22am View

Have you modified Designer.cs file manually? That's never a good idea.
Do you have any compiler errors when you build app?
Are you able to run app? Is menustrip visible when you run it?

sjelen 1-Jul-13 7:28am View

You have that line in two places in your code. Which one causes the error?

sjelen 27-Jun-13 9:49am View

The problem can be anywhere form network connectivity issue, remote database configuration to local connection string.
Try to ping remote host to see if network is OK.
Are you able to connect to remote database using MySQL admin tools?
Does the database you're trying to connect to allow remote connections?
Check IP/hostname and credentials in your connection string, user and password might be different for remote database.

JavaScripSerializer is available since .NET 3.5 and you need to reference System.Web.Extensions.dll

You could also use a very popular library Json.NET: http://james.newtonking.com/pages/json-net.aspx
or if you don't want 3rd party library you can use System.Runtime.Serialization.Json.DataContractJsonSerializer class:

Good point, OP did not specify from where he will be consuming web service, I just assumed it's from browser.

sjelen 25-Jun-13 9:43am View

The event handler code does not need to be in treeview class. You can put it in your richtextbox class and it'll have access it needs.
Then, in main form, right after both treeview and richtextbox are instanced you can wire up treeview event with handler from richtexbox class, something like:
MainForm.MyTreeView.Click += new System.EventHandler(MainForm.MyRichTextBox.MyClickHandler);

Not enough details, but it looks like javaScript problem. Provide the code for OpenChild function.
Is your grid inside UpdatePanel? Does it trigger server-side events?

Do not edit design file manually, it's auto generated whenever you change something in designer and you might loose your code.
Set your event handler from designer or from code in .cs file, never in .designer.cs

sjelen 13-Mar-13 11:22am View

I think the error was in arguments string, it was:
D:\JMeter\apache-jmeter-2.8\bin>jmeter -t D:\TestRun.jmx
should be:
D:\JMeter\apache-jmeter-2.8\bin\jmeter -t D:\TestRun.jmx

I corrected it.

Rewriting URLs in web forms app is not that easy, ASP.NET depends on file extension to find appropriate handler for a request.
Also some server controls render URLs in their output, so you would need to rewrite both request and response.
If you're making a new application and want URLs to look like that, consider using ASP.NET MVC framework instead of web forms.

sjelen 11-Mar-13 13:43pm View

It's a bad idea to have connection strings hard coded in .cs files. Put your connection strings in a config file (connection strings section) and make your app read them on start. That way you can change them easily without editing and re-compiling the code.

sjelen 11-Mar-13 10:20am View

What have you tried? What is the problem?

sjelen 11-Mar-13 8:07am View

Managed code runs inside CLR (Common Language Runtime) which has it's own memory management including a garbage collector.
Unmanaged code runs directly on top of OS (no runtime enviroment, no garbage collector).

Unmanaged code can't access managed memory directly (I guess that's the error you're getting). You need to copy data from managed memory to unmanaged memory and use that copy as parameter to unmanaged method. The result from unmanaged method also has to be copied back to managed memory before it can be used by managed code.
This process is called marshaling and Marshal class has many methods to make this easier.
In some cases can also be done by using 'MarshalAs' attribute on parameters and return type.
Take a look at articles I added above.

sjelen 8-Mar-13 12:11pm View

Improve your question with some relevant code, so we can see what you are trying to do.

sjelen 8-Mar-13 7:15am View

How can you expect anyone to help you when you did not provide any relevant information.

sjelen 28-Feb-13 13:03pm View

One problem could be that you're not closing all data readers when you finish reading.
The other is that you are 'nesting' readers and this increases number of concurrent connections.
Try redesigning your code to avoid this nesting.

sjelen 27-Feb-13 7:01am View

The assembly you're referencing was probably compiled only for x86 (not for x64 or 'Any CPU').
You can either try to find x64 version of assembly, or you can compile your application explicitly for x86 (in VS: Project properties -> Build tab -> Platform target)

Post a example of how you use AddTemplateToGridView if you need more help.

sjelen 21-Feb-13 8:39am View

To access a control on postback you can use FindControl method on a container control.
For this to work, the whole control hierarchy must be created. It's done automatically for designer controls by designer-generated code during page Init.
But for runtime generated controls you have to make sure all controls are re-created on postback.
(Read on ASP.NET page life-cycle)

Post a example of how you use AddTemplateToGridView if you need more help.

sjelen 21-Feb-13 6:59am View

this is C#, use :
images[i]

sjelen 19-Feb-13 12:59pm View

Look at the stack trace of exception - it should point you to the relevant piece of code, where the problem lies.
Are you using recursion? That can cause problems.
Look for memory allocations (using of 'new' keyword), specially with any large objects your app may use and inside large loops.

sjelen 8-Feb-13 5:40am View

Yes and that is why your app works on dev machine - component is registered after the build.
Regasm does more than create .tlb, it also creates registry entries so Windows knows where to find your library.
If you want app to run on other machines you need to run regasm on each machine you want to use.
Or create installer to do that for you.

sjelen 6-Feb-13 7:44am View

You'll need to know the inner workings of CArchive or at least the structure of binary file it creates.
What exactly did you try, that error does not seem to come from FileStream alone?
A code sample would be helpfull.

sjelen 6-Feb-13 7:18am View

See the code in updated answer.

sjelen 5-Feb-13 12:37pm View

You probably didn't make the request right, so the server responded with 'internal server error'.
Maybe you used bad URL, or forgot to authenticate if needed.
The error is not because you used WebRequest class, but because target server could not process your request.

Why don't you try using WebClient.DownloadString method (http://msdn.microsoft.com/en-us/library/fhd1f0sw.aspx)
It will download the page as a string.

Or add a code sample so we can see what you're trying and help you find the problem.

sjelen 5-Feb-13 7:45am View

What is the question? What exactly isn't working? What have you tried? Improve your question.

check your javascript, either your function is not declared to be visible from page or there is js error somewhere before function is declared and processig of .js file is aborted.

sjelen 1-Feb-13 9:08am View

check if any errors are reported by sql server.
Since you use integrated security, it's possible that account you're running from does not have privilege to create database.

sjelen 31-Jan-13 10:54am View

Which version of MSAD Engine did you install, 32bit and 64bit?
Also is your app compiled as x86, x64 or AnyCPU?
Your app and driver need to be the same version - otherwise app can't load excell driver.
If you compiled as AnyCPU, I guess it will be executed based on OS version (and installed .NET version).

Also, on download page it states that this library should not be "called from server-side web application such as ASP.NET"

sjelen 31-Jan-13 10:37am View

I don't think it's threading problem. If it was you would be getting error on development machine too.
If I understood correctly, you made COM component using C# and SerialPort. Then you use that component from VB6?
If so, I guess you forgot to register that component on other machines (or re-register when you changed something) and your app can't load it.

sjelen 31-Jan-13 7:09am View

+5 for you effort :)

One thing you missed:
c = a - b;
textBox10.Text = c.ToString(CultureInfo.CurrentUICulture);
long status = Convert.ToInt64(textBox10.Text);

last line is unnecessary, 'status' will always be equal to 'c', no need for double conversion.

Seems like big-endian/little-endian conversion problem.
Why don't you try to fix endianness while reading bytes from the device instead of messing around with strings?

Is this error exactly on this line of code? What type of object is 'combobid'?
What kind of application are you making: web-forms, MVC, win-forms, WPF, SilverLight?

I can't help you without more info.

I guess you're making desktop application. My original solution is for web application.
You should use 'combobid.SelectedText' or 'combobid.SelectedValue.ToString()',
depending on how you bind data to combo box.

Go to "Tools -> Fiddler Options -> Connections" and check "Act as system proxy..." and delete anything in "Bypass Fiddler for URLS ...."
Remember the listening port (8888 by default).
Add this to app.config of your client app (change the port if not default):
<system.net>
<defaultproxy enabled="true">
<proxy bypassonlocal="False" proxyaddress="http://127.0.0.1:8888"/>
</defaultproxy>
</system.net>
Also you might need to add 'bypassProxyOnLocal="false"' attribute to your binding configuration.

sjelen 17-Jan-13 11:27am View

In that case I would use port forwarding. You'll need to forward port that your chat application uses and map it to the local network IP address of the computer you want to connect to. It's easier to setup if your computer uses static local IP, not DHCP.

And please use "Have a Question or Comment" button to post additional question, do not post a question as solution.

Also consider using basicHttpBinding, it supports transport level security (SSL) and in many cases that's enough. It's much easier to code manually.
Use wsHttpBinding only if you really need message level security or other WS extensions.

sjelen 17-Jan-13 7:08am View

That's because you wrote it like that. You're not reporting real progress, just simulating it.
cdr.OpenDocument obviously works synchronous, so while it works your loop for 'progress reporting' is not executed yet.
I don't know what library you use and what is CorelDRAW.Application object, so I can't help further.
You can report real progress only if this object supports that. Does it have some events you can attach to?

Or you can cheat :) : have 2 background workers, one to open the document, the other to fake progress.

sjelen 20-Dec-12 8:07am View

What does 'unable to call' mean? Are you unable to build the code or are you getting errors/exceptions?
Or your function just does not get called?

In theory, you could use BLOB field to store video in db as binary data.
In practice, this is not a good idea. Relational DBs often have poor performance, specially with large binary data like video. Streaming the video from DB is also problematic.
If it has to be in a database, you should try some NoSql engine like MongoDB.

Did you opened it in some editor?

sjelen 4-Oct-12 6:55am View

Ok, you're right. But your original code was replacing first occurrence in whole text, not in each line, and the problem was not in ReplaceFirstOccurrance but in Transform_Click.

Is DetailsView1 inside 'editPanel'? I just saw that you're adding this panel to ModalPopupExtender at runtime. Why would you do that? Where is 'editPanel' located initially?
When you execute "ModalPopupExtender1.Controls.Add(editPanel);" you change page's control tree. On next postback (update) if you do not do the same asp.net does not know where to find control (it looks in the original location of editPanel instead inside extender.
Can you remove this line and try again? This is not the way to use this extender anyway.

sjelen 24-Sep-12 11:57am View

That would mean ASP can't find the dropdown control.
Is 'ddlfunctions' declared in markup or do you add that control dynamically at runtime?
Can you show markup for DetailsView1?

sjelen 24-Sep-12 11:35am View

You can't. You need a way to uniquely identify a record you want to delete in the database.
Otherwise, you might accidentally delete multiple records.
DataGrid's row number does not have anything to do with database - it's generated in code, not in DB.

Try to add it page OnInit override. That's earlier in page life-cycle so runtime will have a chance to parse values from request for you.

What part you don't understand?
ReadHexFile() reads a text file that contains hexadecimal representation of binary data into a byte[].
Regex is user to eliminate all whitespace an other non-data characters.

In your code you expect that each row have 6 columns. If one of your CSV files has less than 6 columns you get that error. Depending on CsvFileReader maybe if even a single line in a file has < 6 colums you get the same error.

sjelen 18-May-12 5:47am View

in that case you probably got the column name wrong. Can you put your TemplateField markup here?

sjelen 18-May-12 5:43am View

In that case TextBox is definitely bad choice. As Dave said, none of the form controls can achieve that refresh rate. If you just want to measure throughput why don't you (instead of displaying all data) just read the data from USB, get the number of bytes/frames read, use that to calculate current speed periodically and display speed in TextBox.
Anyway, even for drawing a waveform you'll need a buffer. Then myEventCatcher could read the data as it arrives from USB (as fast as it can) and store it in the buffer. On the other end you can have display control process/draw that data at it's own (slower) speed.

Do you have multiple records with the same IDName?

sjelen 14-May-12 6:40am View

And what is the problem?

What type of session do you use? in-proc, state server or SQL?
If you use in-proc (default) you're probably loosing session due to application restart/appdomain recycle.

sjelen 25-Apr-12 6:58am View

There is no universal regex for this, you must specify exactly all formats you want to match.

sjelen 20-Apr-12 7:16am View

This is not actually binding - just rendering a table on client side.
It will display the data, but sorting, paging or editing on GridView will not work this way.

Where exactly is the problem in the code you posted?
You don't need (and can't have) 2nd sessionState to work with 2 databases.
You only need to declare 2 connection strings in web.config, one for each database you use.

It's possible I got him wrong, but he did left out the code used for comparison. So I assumed the problem arose when he set SelectedValue and DropDownList must (internally) use string comparison against it's list of values to find selected item...
I completely agree with conversion rules, you already got mu +5 for that.

sjelen 12-Apr-12 7:20am View

In the example above ItemTemplate has an Image and a Label below it. You can bind your text to it. It doesn't have to be a Label, depends how you want it formatted.

sjelen 12-Apr-12 7:15am View

No offense, but "use HTTPHandler" is a bit more direct then "as described in hundreds of resources."

sjelen 11-Apr-12 13:34pm View

First, selecting actual image data is not necessary for binding to DataList - only an id of image. The way you wrote select might lead him to do just that and in this case image data would only create unnecessary SQL traffic.
Second, "as described in hundreds of resources." is not very helpfull to an obvious beginner. You could have provided at least a link to one of those resources.
No hard filings :)

sjelen 11-Apr-12 13:18pm View

True, but I think this is not the issue here. DropDownList.SelectedValue is a string, so he must convert whatever data type he uses to string in order to set selected item.

sjelen 11-Apr-12 12:52pm View

String.Format("{0:hh}", oDateTime);
should format like 04.
Can you show how do you bind or populate dropdownlists?
Maybe text in dropdownlist items are '01', '02',... and values are '1', '2'?

sjelen 11-Apr-12 12:15pm View

How would you bind an image to DataList?

sjelen 10-Apr-12 13:25pm View

This is correct, but editing 'hosts' file on intranet clients or registering alias in intranet DNS is also required. Otherwise, clients will not be able to resolve site alias to a IP address.

sjelen 10-Apr-12 11:37am View

Edited: was "hh:ss tt", should be "hh:mm tt"

sjelen 10-Apr-12 11:25am View

I see you're using ViewState to store DataTable.
But do you restore objDT from ViewState on postback?
You should do that before adding new row.

sjelen 6-Apr-12 6:07am View

This should be very easy to solve using LINQ

sjelen 5-Apr-12 9:07am View

Both solutions below will work, but you should consider having two separate columns in database. How would you sort records by last name in your current database?

sjelen 3-Apr-12 6:38am View

Your question is not clear, improve question with more details/examples.

sjelen 29-Mar-12 7:37am View

You want "Name" centered across "Name1" and "Name2"?
Try:
dgi.Cells.Add(new TableCell { ColumnSpan = 2, Text = "Name", HorizontalAlign= HorizontalAlign.Center });
Or if you're using CSS class to style table:
dgi.Cells.Add(new TableCell { ColumnSpan = 2, Text = "Name", CssClass="..." });

sjelen 28-Mar-12 5:41am View

Yes, checking would be a good precaution, but since both iDefaultServerID and list of servers come from database I assumed the data is OK. Anyway you don't need a loop to check this, see updated solution.

sjelen 28-Mar-12 5:32am View

Put a breakpoint in SetupServerCombo() and look at the data returned by PlattyData.GetServers(), specially the first row. Does anything look strange there?

sjelen 27-Mar-12 11:37am View

cmbServer.SelectedIndex is already integer, no need to convert it.
You didn't show how you populate combobox items.
And the error probably is not caused by: cmbServer.SelectedValue.ToString()
It's Convert.ToInt32() giving the error, as it can not convert the value to int.
Put a breakpoint on that line and see the value of cmbServer.SelectedValue.

sjelen 19-Mar-12 13:52pm View

'data itself' means the actual recorded sound.
It's usually a byte[] containing recorded data.

sjelen 19-Mar-12 13:37pm View

Again, there is nothing wrong with this piece of code. The error must be somewhere else. If you can, post all your code, maybe we can find what's wrong.
What kind of device is attached to serial port?
Are you sure device is sending data continuously? You might need to write something to serial port every time before you can read from it.

Where exactly did you put this code? In a button click handler? Or in BackgroundWorker DoWork handler?

sjelen 19-Mar-12 11:48am View

The code under your question is correct. You need to provide more details about your application if you want more help, as Wes Aday said.
Does it work at all? Does it work only once?
Is the device connected to RS232 supposed to send data continuously, or you need to send 'read' command to it every time?
The code inyour question does not match the code in your comment above. Which one do you use?

sjelen 19-Mar-12 10:41am View

Is the price for mango and peach same?
If it is then that's your problem - you're using fruitCost as DataValueField.
If 2 items have same price you have no way to know which one is selected.
You should use some unique value for each item.

sjelen 19-Mar-12 10:08am View

Why downvote this solution? It's the same as Clifford's.
Don't downvote something only because you're too lazy to do some research.

Often those machines are connected via serial port so you would probably have to use System.IO.Ports.SerialPort class to read data from it. But the actual communication protocol depends on machine you're using.

There is an article here you could use as starting point:

Using System.Net.Mail does not turn your app into SMTP server. You can use it to make your app act as mail client, just set it up with same SMTP parameters you would use to configure the standalone email client (smtp server address, user credentials).

In that case you don't need TcpListener, look at updated solution.
I didn't try it but it should work.

sjelen 9-Nov-11 7:51am View

What you are trying is something like 'zone transfer' - it is used to transfer all records between master and slave name servers in a domain.
In theory, this can be done by querying for "ANY" or "ALL" on the authoritative NS.
However for security reasons this type of transfer is usually restricted only between trusted IPs or networks, so you will not get all records.
In another words - it is only possible with name servers that allow zone transfer.

Not a complete solution:
'unload' event fires every time user navigates to another page, and to do that he doesn't need to click anywhere on <body>
He could use 'Back' or 'Forward' buttons or enter address manually.

Do you mean public static internet IP of your modem or LAN static IP of your modem?
In first case, look at second part of "Answer 2" - that's probably the easiest way.

Correct about ViewState, this also applies to anything using encryption (like EventValidation).
However MachineKey does not have anything to do with Session. Setting up session in a web farm is complete different problem (you can not use in-proc sessions).

sjelen 23-Dec-10 8:39am View

why create Color instance from bytes, then convert color components to strings, just to convert those strings back into bytes?

Right,
You can not use GetPixel() after you call LockBits() on same bitmap. That's why you get memory errors.
