There is no "event" as you call it. AFAIK, there's not even a callback. I think you would have to enumerate the windows in the taskbar, keep a list of them, then enumerate them again every so often to see if the list changes. When the list changes, the know an app has been launched or has quit. The problem with this is that an app can run and end inside of the time you have for a polling interval. You'd never know an app was launched.

Probably by implementing either a GetMsgProc[^] hook or a JournalRecordProc[^] hook. Neither of which can be implemented in managed code (VB.NET or C#).

Hi,
using one or more external web sites is the only way I really trust for this to work reliably.
Have a look here[^].

The only way it works reliably is if you use a website external to your network.

That list is quite long, on the order of a few hundred files. Since it sounds like you never created installers for these applications, you're only real recourse is to reinstall Visual Studio 6. If you had created installers for these apps, you would just have to reinstall the apps, or run a Repair on .MSI installers, to replace the missing files.

Firstly be aware that I have never used VB6.
However, all previous versions of VB (v2.0 - v4.0) that I have used, required the run-time redistribution pack to be loaded on machines using apps written in VB. Therefore you might want to look at Visual Basic 6.0 Runtime Redistributable[^] page on MSDN.
If I am way off base, please ignore this.

If you are still using VB4 you are a little off base, otherwise all is fine.

Not still using, although I still have the Disks for VB3.0 lying about somewhere in a glass case labelled "In case of emergency, throw away"

Well, if the installer was written correctly, it should already have all the components it needs to run the app inside the installer. They should all be installed with the application. The only thing that would not be included would be the VB6 runtime. That's installed seperately.

Can we exclude designer.vb file in windows applications using Visual studio 2005?
|
|
|
|
|
The designer files are just code to create the form and it's controls and lay them out on the form. Why would you want to execute just that file?? To answer you're question, no, you can't execute just the code in that file. All the files for the form are compiled into a single object that has no idea it was created from multiple files.

He said "exclude", not "execute". (Or maybe he edited the post.)

Hi,
1. when you create another kind of project (say a Console app) you wouldn't get a designer file at all; you then can edit and add Windows.Forms code (or any other code) to the files you do get. That excludes designer support of course.
Also, you can copy-paste the designer code from where it is to where you prefer it to be, then remove the designer file. The designer may or may not still work for you then (I do it sometimes in C#, I have no experience doing this in VB.NET).

The last time I tried this, it broke the designer. Though, I can't rememer if it was VS2003 or VS2005.

Hi Dave,
I just finished this[^] test app using VS C# 2008 Express; with the InitializeComponent() stuff inside the main file, all works well, the designer locates and keeps updating its code just like older VS versions used to do.

Cool. I never tried in in 2008. I don't have it installed anywhere at work yet.

Interesting!
I spend a fair amount of time doing the opposite, converting .Net 1.0/1.1 code to have a designer.cs file, since I prefer that.

So did I, when switching away from older .NET and VS versions.
However for very small projects (less than 100 lines of code) I prefer having it all in 1 file.
BTW: this may interest you, long ago, working in Fortran under RSX11D/RSX11M/old versions of VMS, I used to put build commands at the top of my FTN sources, starting with a 'C' of course; and I had a small utility to invoke compiler, linker, and then run the program. So the entire project was 1 file, which built and ran automatically.

I created an application in vb.net 2005. It works fine on my machine. I tested several different test machines and all were working fine. As for the client, it's generating an error. My application reads from an excel sheet and imports the values to an oracle database. the error being generated is: "conversion from type string to type double is not valid". Why is it generating on on the client's computer and not mine?
