Getting the installation directory in a Deployment project - C# Discussion Boards

Re: A Little Problem in Single Instance Implementaion!!!

3-Aug-06 6:40

Hello,
First of all please do not refer any previous articles on this website about my problem and try to point the problem and its solution.
Thanks in Advance!!!

I'm written some implementation about Single Instance Application. All is working fine.

When I run the second instance it stops itself if one already running in the following states of the main Form:
1) minimised
2) maximised
3) Normal

The only thing that is not working fine when the main Form is Hidden becuase of Form.Hide(); or Form.Visible = false;

Here is the code which i'm using to show the instace of already running application:

if (IsIconic(hWnd))<br />
                    ShowWindow(hWnd, SW_SHOWNORMAL);<br />
                else<br />
                    ShowWindow(hWnd, SW_RESTORE);<br />
                UpdateWindow(hWnd);

Please suggest an accurate solution to this problem.
I'll be really thankful to you.

Best Regards,
Rizwan Ahmed.

I am using a Deployment project to deploy my C# application (VS 2003). In the Uninstall event I want to get the installation directory that was selected by the user when they installed the program but can't seem to get this.

Application.StartUp path returns the path to the msi file that is executing not the installation directory.

Strange Problem Regarding TabIndex

Hello Devs,
I'm facing a very strange problem in Windows Form Application using Visual Studio 2005.
I have a lot of controls on my Windows Forms like TableLayoutPanels, TextBoxes, RichTextBoxes, Buttons.

I set their TabIndexes appropriatley from 0,1,2,3.....
When I run the application The cursor focus is not on the control whoes TabIndex Property is se to zero Mad | :mad:

.
I need to Focus myself on the control I want to be focued when application runs.

I'm stucked with this for more than 6-7 hours, Removed all the resource file Entries of TabIndex and set all of them again. (Didnot work).

Tried to Set focus on tha control in Form's Load event (Didnot work too).
Also Saw the Property in Form's Load even that if that control can be focused using Control.CanFocus (Always Returns false).

Please tell me something about this Bull S*** Mad | :mad:

Its a pain in A** for me at this time.

I'll be really thankful to you for your help.

Best Regards,
Rizwan.

I once had the same problem. I had to put the focus on the control I wanted with control.BringToFront();

I don't know why the TabIndex sometimes don't work with VS2005, but I didn't found the error. After I reinstalled the computer (and VS2005) it worked fine.

Regards,
Ingo

Hmm, Its impossible to reinstall all the things again. But yes you are so true this is some bug with VS 2005 coz my friends also complained me about this when i discussed my problem with him.

Anyways there are 2 possibilities:
1) I Compile it at some other computer.
2) I use the method you used control.BringToFront();

Can I put control.BringToFront(); in Form's Load Event?

Can you explain the code:
Should I use this:

control.BringToFront();
control.Focus();

in Form's Load Event?

Thanks a lot for your reply,

Best Regards,
Rizwan

tried this: (Didnot work)

private void FrmServer_Load(object sender, EventArgs e)<br />
        {<br />
            rtfSend.BringToFront();<br />
        }

Nor this:

private void FrmServer_Load(object sender, EventArgs e)<br />
        {<br />
            rtfSend.BringToFront();<br />
            rtfSend.Focus();<br />
        }

Nor this One:

private void FrmServer_Load(object sender, EventArgs e)<br />
        {<br />
            rtfSend.Focus();<br />
            rtfSend.BringToFront();<br />
            rtfSend.Focus();<br />
        }

Any Help?? Confused | :confused:

Thanks a lot

That's strange, but I don't get the same error now, so I can't test it.

Sorry,

Ahhhh! Ok, Thanks.
But are you sure Windows and Visual Studio Reinstallation can fix this problem Confused | :confused:

I think this configuration may only reside in Resource files which i refined clearly but not working :->

Thanks a lot,

No sorry I'm not sure. For me it worked, but I don't know if our problems have the same cause.

It might be a good idea to look at the control that IS getting focus when you load your form.

Is it a panel? I've had to set the TabStop property to false on a panel before, even though it had a high tab index.

RizwanSharp3-Aug-06 19:32

3-Aug-06 19:32

Yes,
I have tried all the things, I set all the panels and all oher controls' TabStop property to false.
But again the same proble.
When I run the application, The focus of the control must be at the control whose TabIndex is 0 rather it focuses control with TabIndex 2.

When I try check CanFocus property of Controls with TabIndex 0 in Form's Load it returns false.

I want to know the reason what's the reason behind "Control.CanFocus is always false". How does it evaluate this that it cannot be focused. If i know this then may be we can solve the problem.

Thanks alot,
Best Regards,
Rizwan Ahmed.

You need
cnADONewConnection.Open();
before
m_daDataAdapter.Fill(m_dtContacts);

DataAdapter handles the open and close connection in the Fill method

How can I run an executable from within my C# app

3-Aug-06 6:33

Hi,

you are in the wrong board. ASP.NET Question should be asked in ASP.NET Board. Secondly you just use a subject that is corresponding to the problem and not just "hi". Use a subject as: "Printing a datagrid"

I can't help you, as I don't have an active ASP project and my last one was mutiple month ago.

Regards,
Ingo
