Show your code.

Hi Mehdi Gholam,

This is only my code.

This is working fine without setup. This winform i am calling inside web setup project during installation. that time only not working.
if (result == DialogResult.OK) // Test result.
{
txtUploadFile.Text = this.fdDestPath.FileName;
}

sorry i missed one line code for creating an instance for DialogResult DialogResult result = fdDestPath.ShowDialog();

my full code is

DialogResult result = fdDestPath.ShowDialog();

if (result == DialogResult.OK) // Test result.
{
txtUploadFile.Text = this.fdDestPath.FileName;
}

Looks ok.

it is fake becuase dialog result is a property of window that get and set value with showdialog.

In this case, where you believe you've tested your code thoroughly, and it works fine (in a regular WinForm ?), then I think the right questions (hypotheses) are:

1. is it possible that a web-setup project does not allow the use of a WinForms control in this way ?

And, I think, for us to help you with that, we need to see some specific error messages: are you able to compile without error: have you single stepped through the code in the Web Setup project, and observed what happpened when it reached the call to 'ShowDialog ?

Yes I can able to compile and run it without error. Only thing when the same win form run from installer that situation only not working.

And from websetup project i dont know how to put the break point. Because the break point its not happening during installation time.

But I have confident when DialogResult result=fd.showdialog() code is running its not opening. That time in winform title is getting like "Not Responding" and strucking.

hi Mehdi Gholam,

I tested in windows 2008 os. When win form is executing its working fine. But if run from setup its not working.

And i tested in XP os its working fine both mode (with setup project and without setup project)

So i think i should make the changes in properties.

windows 2008 os and 64-bit system the filebrowserdialog and folderbrowserdialog control is not working.

The problem is that the MSI thread is running as an MTA thread, but the FileDialog.ShowDialog requires an STA thread.  To achieve this you will need to start a STA background thread and call the dialog from that thread. Basically I did the following:

-          Added the DialogState class.  This keeps track of the input and output for the thread.

-          Added the STAShowDialog function.  This function takes a FileDialog, calls ShowDialog on a background STA thread, and then returns the results.

-          Changed the call from DialogResult ret = frm.ShowDialog(); to DialogResult ret = STAShowDialog(frm);
