First, wrong forum!
Second, you're ISAPI extension has to accept appropriate data from the form. See the article http://msdn.microsoft.com/msdnmag/issues/01/10/upload/default.aspx[^] for an example. There's some links at the bottom that discuss general ISAPI programming.
While the example is for files, the idea is similar (and more simple) for plain form data. Just like a GET query string that passes a key/value pairs separated by & and associated with =, POST query data is delimited in the same way but uses the content-type "multipart/form-data".

Linking database with C# was easy but the problem that I faced when I was working on my project was when the database and the program was is in local drive(C) and working, then I cut that and put it in my network folder.
After that when I again copy that and put it in c drive and run it, then the links are changed and again I had to put all the links again. That is a rediculous task.
Can any one provide solution for this?

Links? You mean connection strings and what-not? Put the connection string in your application configuration file (yourappname.exe.config) using the <appSettings> section (see the documentation for that element for more information) and use the System.Configuration.ConfigurationSettings.AppSettings to get it out. This is pretty much the common practice for both Windows and Web Forms.

You know... some full screen windows program have those menu bar on top? if you press ESC it will hide and you press ESC again it will Unhide? I like that kinda style but then... I'm a super C#/programming n00b, I only started C# for like a week, I don't know syntax and everything, it would be cool if anyone can show me exact what I should do (I only know the part about adding the menu to the application form by double click the MainMenu in the ToolBox), to add code to make the menu hide and unhide with ESC key, I dunno that one =^^=
please help a n00b

Look at the KeyDown event. There are other events that work similar, but this (or KeyUp) is the easiest since you're passed the KeyCode that was pressed.
As far as how to do it, well, you're going to have to learn. In VS.NET, you can switch to the events tab in the Property Grid, find one of those events I mentioned and double-click it for a default name. Start reading the documentation for the KeyEventArgs that is passed and you'll even find some good examples.
Blindly fumbling through code and relying soly on IntelliSense won't teach you anything. Researching most definitely will and is required for good development skills. If you still can't figure it out, post to the forum what exactly is wrong (compile errors, exceptions thrown, etc.) but try to figure it out first. It's the only way to truly learn especially when you're a n00b.

Your post didn't help at all since I'm a n00b and there are too many topics about KeyEventArgs in the MSDN and there's no example that I was looking for.

Well, there's only one way to learn, bubba. Start reading the topics in MSDN and start-off basic if you can't understand the "advanced" (even though it's not) stuff. Making guesses and asking others for complete examples won't teach you anything.
Here's a (rather thorough) tip, though: handle the KeyDown event and in the KeyEventArgs check if the KeyEventArgs.KeyCode property is set to KeyCode.Escape. Then either call Show or Hide on the Form. The only problem is that once the form is hidden, it won't receive keyboard events because it doesn't have the focus. So, you'll have to have another Window that is capable of showing the window again if the [ESC] key is pressed again.

wha?? that's bullshit and so much trouble, I saw other programs made in C++, it doesn't look so hard and hassle, I start off with C# because I thought it's easier than C++, now I think C# is bullshit, so little examples to learn from and people aren't even helpful, there are tons of examples with C++ about that hide/show menu but I wanted it in C# but no examples....

Look, a window can't receive input if it doesn't have the focus! Period. If can't have the focus if it isn't visible! Period. If you don't believe me, read the damn Windows Manager section in the Platform SDK. The only other way is to install a hook and remove it when visible again.
And it's so much trouble to actually READ the documentation? Right. You'll learn a lot that way.

I currently have a collection of custom business objects which is a datasource for my DataGrid. I would like a property of this custom object to be an image which is displayed in the datagrid. I am using column styles and DataGridTextBoxColumns for all other properties. How do I display an image?
I need the solution to be generic, so I can't be using delegates or other solutions that require a hardcoded function for a particular image.
I have not found anywhere on the net that describes how this can be done. Does anyone have any sugguestions?
Please help.
Thanks.

I’m pretty sure that you'll find all that you need about DataGrid at
Windows Forms FAQ:

I think this is a valid solution. Any Sugguestions?
I have created a class called GridIconOnlyColumn which implements DataGridTextBoxColumn
protected override void Paint(System.Drawing.Graphics g, System.Drawing.Rectangle bounds, System.Windows.Forms.CurrencyManager source, int rowNum, System.Drawing.Brush backBrush, System.Drawing.Brush foreBrush, bool alignToRight)
{
try
{
g.FillRectangle(backBrush, bounds);
if (mobjGrid == null)
{
mobjGrid = (Prud.Controls.Grid)this.TextBox.Parent;
}
// Get Custom Object
object objRow = mobjGrid.Rows[rowNum];
//Draw Image
g.DrawImage((System.Drawing.Image)PropertyDescriptor.GetValue(objRow), bounds);
}
catch (Exception err)
{
throw err;
}
}

Assume my windows based program is named 'App1'.
How can I write
If App1 == Already running
{
then exit and do not run a second instance
}
thanks

using System.Diagnostics;
In the Main function for your app...
Process proc = Process.GetCurrentProcess();
Process[] procs = Process.GetProcessesByName(proc.ProcessName);
if (procs.Length > 1)
Application.Exit();
else
Application.Run(new Form1());
|
|
|
|
|
|
Jeff,
Shouldn't that read:
if (procs.Length > 0)
Thanks,
Alvaro
He who laughs last, thinks slowest.
|
|

|

No. The first instance of the program would never run because the Process array includes the current running process. So changing it to Length > 0 would cause the program to never run.
|
|
|
|
|
 Of course!
Thanks for clarifying.
Regards,
Alvaro

While getting the process list is one way to do it, it relies on nobody else running an executable with the same name.
The approach most people seem to use is creating a "named mutex". A mutex is an object that can only be owned by one thread. If you make this a "named" mutex, then its effect is machine wide (as opposed to just process wide).
The approach is you try to create a named mutex with a unique name (use a GUID and you'll never have to worry about some other program using the same name). If you are able to create it and own the mutex, then you're the first instance running. If you can't create it, someone else is already running.
For an example of this technique, use this link I found in a Google search:

I have a form that I need to set a vlaue in from another form. I know I can do this with a property. the problem is that form I want to set the property on is already active. The olny way I know to set the property is to do somthing like
formname f = new formname();
f.propName = my vlaue;
f.show();
this would create a new form not use the one I already have and I am at a lost as to how to set the prop in the form that is already loaded.
thanks for any help.

in your main form clas create a member variable (reference)
formname f;
in the load event of the main form :
f = new formname();
then in your code:
f.propName = my vlaue;<br />
f.show();
this way you always use the same formname instance..
i wish this can help..
|
|
|
|
|
dose this not create a new instance of the form and not reffrence the one I curently have open.
I was able to make it work by making it static. Is this a good way of doing it or did I gat lucky 
|
|
|
|
|
I think my way (member variable) is more clear nad reasonable.
