Hi Griff,
Your code works.
I must be blind-as-a-bat tonight. fyi: I tried reversing the order of creating memorystream and gzipstream ... still using only two levels of 'using ... and got the same error.
Sascha also had a valid solution here: I was leaving the file open by my setting the Gzip calls 'leaveOpen flag to 'true.
But, your code adds an additional level of 'using that takes care of the "in-use" error independently of the value of the 'leaveOpen flag in the calls to GZip.
thanks, Bill

Hi,
Can you help me ? I am try diable that MainForum run again form volumepanel. I want this:
When i am goto to top of screen the mainform show only ove volumepanel.
Here is code:
X = Cursor.Position.X;
Y = Cursor.Position.Y;
if ( Y == 0 ) {
if (( Application.OpenForms["volumepanel"] as MainForm ) != null ) {
MessageBox.Show("fdf");
} else {
volumepanel vpanel = new volumepanel();
vpanel.Show();
}

I'm sorry, but I think you need to be more specific.
Personally, I have no idea what you're trying to achieve.
Best,

i am developing Dekstop Manager for disabled peoples, contolled with eyes.
If user goes to top of the screen:
X = Cursor.Position.X;
Y = Cursor.Position.Y;
if ( Y == 0 ) {
Exec this code:
volumepanel vpnelc = new volumepanel();
vpnelc.Show();
And show volumecontrol frame. The problem is that open in loop volumecontrol frame when user stay with mouse on top. I am need protect that show only one volumecontrol.
Here is captured the problem:

Then before you open the volume control you need to detect if it is already opened!

From your first message:
if (( Application.OpenForms["volumepanel"] as MainForm ) != null )
Is the VolumePanel-Form actually of the type MainForm? If not, the as-keyword will make the expression left of the equal-sign null, so that your if-check fails although the VolumePanel actually is open.
Also, since you're using the return value of Application.OpenForms["volumepanel"] only for checking for null you don't even need the as-keyword here.

Without seeing your code, I can only propose an answer that I think will work independent of your UI design; if I could see your code, I'd probably propose creating a "local" boolean variable.
1. set a global static variable 'IsVolumeControlShown
public static class ApplicationGlobals
{
public static bool IsVolumeControlShown = false;
}2. when you get the event notification to show the VolumeControl:
public EyesAtTopEvent(????, ????)
{
if(! ApplicationGlobals.IsVolumeControlShown)
{
VolumeControl.Show();
ApplicationGlobals.IsVolumeControlShown = true;
}
}3. When you get the Event to hide the VolumeControl:
public EyesNotAtTopEvent(????, ????)
{
if(ApplicationGlobals.IsVolumeControlShown)
{
VolumeControl.Hide();
ApplicationGlobals.IsVolumeControlShown = false;
}
}Note: this is not code I would actually use, but an example I hope will indicate to you a "path to follow:"
0. create the VolumeControl whatever (panel ? form ?) once and keep a reference to it where you can access it.
1. use a variable to control the visibility of the VolumeControl
2. use that variable in the right place to show/hide the VolumeControl as needed.
Note: "ideally" you would be so "in control" of the code that you would be certain when you were showing or hiding the VolumeControl, in which case you would not have to check the current visible state of the VolumeControl every time you needed to show or hide it. However, imho, the kind of "defensive programming" shown here ... the visible state check ... is often useful in UI work where events may happen at a high frequency.

Hello
I need to create a sw that send SMS from a c# form using a Sony Xperia E4.
1) I cannot find the AT command to drive the smartphone
2) I cannot find the way to assign the correct portname to the usb port I connect the smartphone to.
I am using System.IO.Ports .
Then I make this nameport.WriteLine("AT+CMGS=" + Celnumber + "r") but here code return with exception.
Regards
Roberto

The AT commands are documented all over the web. The command set is standardized, with vendor specific extensions. A little Google goes a long way[^]. Sending an SMS normally doesn't use any vendor extensions.
As for "assigning a port", your code doesn't do that. You have to get that information from either from the user or your code can take an educated guess at the port name. Example[^].

Hi All,
I want to create my own report builder for our windows or web c# application, for each project we are build we must create a reports my need is we want to build the report builder and we can add it to any project and create the reports using this builder dynamically.
Please let me know if there is a tool can do that or how we can build this tool.
Thank you all

There are many component vendors out there who provide exactly this. I like the Syncfusion options, but you can choose any of the major vendors (DevExpress is a popular choice).

ok, look for my need.
1. create windows/web application that can connect to a database.
2. choose type of report from procedures, or from views
3. then we choose the report type is pivot or not
4. we have 3 list first for row header, second for column header, and the last for the sql operation such as sum, count, max
5. if the report is not pivot the it will be a normal select, and we drag and drop the view fields name to the column header list and if there is an sql operation we drag a field over one of them (sum, count,....), and create the select
6. if the report is pivot we drag fields for the column header, and fields for the rows header, and fields for the operation if found and we create the pivot select.
7. after that we save this select to a report database contains report name , select query, report classification.
8. in each application we build the reports from these database in the application menu and we can view the data and print it using the shown screen which is built in the dll or api that we can create for the web and for the windows
please let me know if this is possible or not, or if there is a tool can we buy it to use and don't create our own one.

Please stop spamming the thread with your requirements. This isn't a code-on-demand service where you list your vague requirements and someone spends days coding a solution for you. If you can't do this work yourself then look to hire a freelancer.

The amount of code is incredibly complex and very time consuming to do this yourself. As such, there is no way we can tell you how to do it here. It all depends on how much control you want to give your users.
I suggest using a tool like Microsoft SSRS and it's Ad hoc report builder or some other tool that already exists.
There are only 10 types of people in the world, those who understand binary and those who don't.

I use the DevExpress reporting system, and I find it very easy to use. For a basic GUI report builder you don't really need any code, it's all handled by the reporting framework. You can build reports dynamically in code as well with the framework.

That should be possible with the DX controls. Quite a bit of code would be needed, but the framework should help with that.

Your expectations are a long way beyond a report builder, any report builder. All of them will handle to design and layout of the reports you require, deciding on the layout of the report is up to the user designing the report, not the report builder software.
Storing the query and report code into a database is up to you to build. I have done all of the above using a number of reporting tools over the years so there is nothing new about your requirements. It will require you to a lot of work managing the infrastructure.
You will not need to create your own report designer, use one of the commercially available ones.
