I am trying to install a merge module with the following command:
msiexec /a Microsoft_VC80_DebugCRT_x86.msm
My system displays a Windows Installer dialog that says - "Preparing to Install...". Then the dialog disappears.
After this, I go to C:\Program Files\Common Files\Merge Modules\ and the msm does not exist in the directory, although I am expecting it to.
What am I missing?

I added the merge module to a setup project and the merge module installed successfully.
Has anyone on this forum used msiexec to install merge modules? If so then please take a look at the command in my last post and let me know what might be wrong.

Ok, I've got this project which I've been developing for about 9 months now as a .NET web application. I was told today that we're switching gears and it's going to be a Windows app instead. Ok, slight problem. I know exactly two things about Windows app development, Jack and S**t. And guess what, Jack's just left town. So I throw myself upon the mercy of the gurus. Can anybody point me to a good tutorial on WinForms that talks about a multi-form application and using menus to switch between active forms. The only WinForm app ever developed by anyone at work was a small demo app that had two forms with a button on form 1 to hide form 1 and show form 2, then a button on form 2 to hide form 2 and show form 1.
I've tried googling for some tutorials and I'm coming up with nothing helpful. Anyone got any ideas?

Well, the main thing is, you just show a form by creating an instance of it and then calling ShowDialog or Show, depending on if you want it to be modal or not.
If your main form switches between forms, I'd create them as controls, put them all on the form, and swap which one is visible.

That's what the demo app I've got does. But this app is going to be a few hundred forms. It's going to be a replacement for four individual MS Access applications and we're rolling them all into one app as the departments that used them have been consolidated into one. I was hoping to be able to create a menu with some sort of method for showing/hiding controls and when the user clicks on a menu item that control shows and the currently visible one hides. Does that sound reasonable?

Yeah, the way I'd do that is, have an enum of forms, store the enum for the form you want in the tag, then write a method that you call which hides all forms, then shows the one specified by the enum value. So, you have one menu click event, which reads the tag, then turns it into an enum and calls one method that is always responsible for setting the visible form.
You can just iterate over the controls collection to hide your controls. You could even have the controls that are the forms have the same tag values so one function checks each controls tag and works out which one to show, no switch or anything needed.

Thanks Christian. I appreciate your help. I'm going to look into this more when I get to work tomorrow.

Cool - just post again if you get stuck.

Actually what you need is a WinForm with one main form and every form will be shown in the main form, one at a time, right?
You can create the forms as per normal, and instead of calling Show(), do the following instead. The form will be shown in the body of main form.
Form2 form = new Form2();
form.FormBorderStyle = FormBorderStyle.None;
form.TopLevel = false;
mainForm.Controls.Add(form);
form.Show();

Cool - so that basically adds the forms as controls, it's another path to what I was saying ?

Yep, since it's a form as oppose to control, you can change it to MDI easily.

This seems nasty to me.
I think you need to string mash the table name, I don't think that's what parameters are for.

Here is a snippet:
byte[] b = Encoding.Unicode.GetBytes("?"); // ? is a special (arabic) character,
// but my browser shows it as a ?.
string x = Encoding.Unicode.GetString(b);
While debugging, if I inspect my xx variable, I see a square as character. What did happened and why I did not see exactly the same character that the one I initialized b?
I write the a file, using the several encoding options available. When i read my file, I alway get this @#$%! of square character. But if I paste what I have in x in this message, I get --> "?" 
I have a picture of it, but could not attache it 
Thanks

Assuming I've understood you right, the rectangle you're seeing is a representation of a character that is either unprintable, or one that isn't available in the font the Inspector is using (the latter reason is probably also why you got a ? instead of the expected character in your browser). It could also be because the inspector is interpreting the encoding wrong. I'd personally think the second cause is most likely.
To be honest, if the code works correctly (and I can see no reason why it won't if your snippet is anything to go by) I'd just ignore this 'feature' of Visual Studio, and use the clipboard and a decent text editor instead.
Hope this helps

Hello, I made a program in C# with a webrowser that loads a website. the website unfortunately has flash ads.

if it is too much to ask, i would appreciate some code? i already tried google with no success

How do I get disk volume info in C#? (without having to traverse thru all dirs)
the same info as this function in C++:
GetDiskFreeSpaceEx(str, &lpFreeBytesAvailableToCaller,
&lpTotalNumberOfBytes, &lpTotalNumberOfFreeBytes );
Thanks.

You can use DllImport attribute to call GetDiskFreeSpaceEx from your C# code. This is for you to explore: P/Invoke[^]
By the way, DriveInfo Class[^] has quite many information about drives.

Thanks for the help.
I can't get the DllImport to work.
I don't know if it's because of my old IDE (2003).
I've installed up to .net frw 3.5.
System.IO still doesn't have the function "DriveInfo".
When I tried this:
[DllImport("user32.dll")]
public static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);
the error is:
at "bool"
Expected class, delegate, enum, interface, or struct
why?
Thanks again.

DriveInfo class appeared in .Net Framework 2.0 so you need Visual Studio 2005 or later. As for GetDiskFreeSpaceEx pinvoke.net[^] can help you.

Thanks again.
I did try several DllImport code samples from PInvove. They all have the same syntax error.
I think it's my old IDE problem, it cannot open/run most of samples.
I'll need to buy the new .net version (if my boss can get budget for the whole sw group. doubt it!).

You can download Express version of VS2008 and try it there.

I dont have msdn subscription.
we're still using 6.0 (due to limitation of hardware device drivers, and users' hardware). We bought .net 2003 to learn it only.

Well, theres the System.IO.DriveInfo class which gives a little information on a drive:
DriveInfo di = new DriveInfo(@"C:\");
Console.WriteLine(" Free Space: {0}MB", (di.AvailableFreeSpace/1048576));
Console.WriteLine(" Used Space: {0}MB",(di.TotalSize-di.AvailableFreeSpace)/1048576);
Console.WriteLine("Total Space: {0}MB",di.TotalSize/1048576);
1048576 is 1024*1024 because the properties return the number of bytes.
There's also FileInfo and DirectoryInfo classes, incase you ever want to use those too.
My current favourite word is: Bacon!

Hi,
I concur.
Except, if you mean 1024*1024, then why don't you write it like that, preserving optimal
readability? the compiler will do what is necessary and generate exactly the same code...
