Hello friends,

I want to create a installer like we are adding deployment project in our application.

but i want it to be done at runtime from an application.

for example,i have one desktop application.
in that if i will click make installer than it should make an installer
which includes more than one files.
And furher when user runs that installer it will call installer class which makes registry entries for further use.

any kind of help is appreciable

thanks in advance.

lets say i have the folowing connection string:
"Data Source=.\SQLEXPRESS;AttachDbFilename="C:\Project Data\PTMA_database_Data.MDF";Integrated Security=True;Connect Timeout=30;User Instance=True"
the thing is...i have multiple databases, all located in different folders, all folders in c:\Project Data\. the user is supposed to chose the folder from wich the database is suppused to load. But how do i do that...How can i make the connection string look like this:
Data Source=.\SQLEXPRESS;AttachDbFilename="C:\Project Data\"+path+"PTMA_database_Data.MDF";Integrated Security=True;Connect Timeout=30;User Instance=True??

First you use a FolderBrowserDialog to have the user point to the appropriate folder. Make sure you set the default directory to start at the C:\Project Data location.

Then after it comes back you use the property within it to find out which folder they chose. Use debugger mode to confirm what you get back, it may provide your entire path name to the folder. In that case you would have:

AttachDbFilename= Path.Combine( browser.FolderName, "PTMA_database");

Multicast Delegate

When we use the operator "+=" with delegate, does it denote multicast.

i think we use "+=" with delegate when we add event handler to any
event and call specific method to handel that event through deligate.

Events are special kind of delegates, and += are used with events, which means an event may have more than one event handlers. So what i concluded is that += (with events) denotes multicast.

+= is applied on events right? and event delegates are multicast delegates.

ErrorProvider and Localization

Hi,
we approached the problem with .NET ErrorProvider componet and localization. When the form contains errorProvider and its language property is switched to some language mutation and then switched back to default, form looses some settings as for example BorderStyle property or DialogResult.OK on Accept button is changed back to DialogResult.None. Did anybody hit to the same problem ?

toolstrips moving randomly in toolstripcontainer

In my app I am using a ToolStripContainer where one menustrip and three toolstrips are embedded in the TopToolstripPanel.

My problem is that at designtime these strips are moving randomly within the ToolStripPanel after compiling or switching between code and design. Sometimes one toolstrip moves above the menustrip, sometimes, the toolstrips move in one row behind each other.

At runtime the toolbars are alway in the right position.

Does anybody know how to prevent this behaviour?

how to get the system idle time to logoff the system?

hi everybody,

Could somebody pls help me to find a solution for this...
I need to calculate the system idle time (I repeat SYSTEM idle time & not application idle time)
I need to logoff the system if the user is not working not only in my application but he is away from his desk...

so definitely Application.Idle is not goin to work since it just triggers for the particular application's idle time

Thanks in Advance,
Enjoy .Netting

This is a really BAD idea. Have you considered the possibility that the user walks away from his desk with an unsaved document open? If you log this person off, any unsaved changes will be lost and that person might come hunting for you with a large weapon.

First of all thanks for the reply...

I think I was not clear on the issue..
What I'm trin to achieve is a kind of screenlock..
Just as what we have in Windows if the system remains idle for a particular time...

Once again thanks for the reply & keenly look forward to ur replies

Check user in domain

Hello...

I want to check username, password, and domain together. I always used C++ to do that. That means, I give username, password and domain, and the return value is true or false.

Now I changed to C# 2.0. Are there any classes or methods to do that ?
Probably using DirectoryService ?
Can anybody show me the right way how to do that ?

Thanks...

In the button click event, check the .Text property of the textbox and see if it is empty or not.

I'm assuming here that you've already created the Click event for the button. If you haven't then you need to do this first. Then, assuming your textbox is called myTextbox, you would type something like this:

if (myTextbox.Text.Trim().Length != 0)<br />
{<br />
    //... Show the messagebox here and do the save<br />
}

The Trim() removes any spaces from the end of the text. If the user had just pressed space, this would ensure that the messagebox was not shown.

There are many ways to accomplish this test. You could test to see if myTextbox.Text.Trim() == string.Empty.

Brilliant. Thanks for your help... It all falls into place now. Big Grin | :-D

using Trim() ".Length !=0)" works where as "== string.empty" doesn't appear to do anything.

Once again thank you.

"== string.empty" equals to true when the string is empty whereas ".Length !=0" equals to true when the string contains some characters i.e. isn't empty. Use "!= string.empty" to get equal result.

Hi all

Im trying to get this regex to fit with dash but i wont work...

regex:
Regex r = new Regex(@"^(([a-zA-Z] Smile | :)

|(\\[\w]+\-[\w]+)\$?)(\\(\w[\w ]*))+\.(cwp|CWP)$", RegexOptions.IgnorePatternWhitespace);

bold is the critical part tried:
(\\[a-zA-Z0-9-]+)
(\\[a-zA-Z0-9\-]+)

this is the path it should match...
