In an other post of mine, a discussion was going on to change the extensions of mdb so user does not recognize it as Access DB (this is important for me) I tried this and changed extension to xrd, ran the application and it gave error. Off course it could not find my mdb. How to handle this? Do I need to make all the connections again?

I made a library in C# and I've been told by people that one of mine methods don't work in VB.NET as extension [UR]
this is the method:
public static PropertyDescriptorCollection GetProps(this object o)
{
return GetProps(o.GetType());
}
Firstly, I understand that this might sound more or less abstract, but this is because I have no previous experience in such applications. I completed an application using Visual Basic and is running and tested. What I want to do is
to make this application expendable i.e I could write other pieces of code and I would just plug it in to the application "somehow" and it would be added as a functionality.
I want to design an application that can open file of certain extensions. For ex. There is a software called ARJ32 which can open file with extensions
.a00 ,.a01...................,.a19.
Also there is application called apk emulator which can open .apk files. So eve I want to design an application that an open certain file extensions. Is it possible? How do I start? I am well versed with c, c++, Java, VB.NET
Vb.net For each currentFarm in ......
If urlQueue.Count > 0 Then
Debug.Assert(currentFarm.isBusy = False)
Debug.Assert(currentFarm.WebClient.IsBusy = False)
[CODE]...
The commented code won't work. That's because by the time the thread start, the variable currentFarm have changed. So I create a new function and cache the currentFarm in the function parameter. No there will be a cache of currentFarm address (object is always a pointer) on a stack and that address is the one being passed to the System.Threading.Thread constructor.
I have a UserControl that has a ProgressBar on it. The purpose of the UserControl is to be able to show the progress % on the ProgressBar as text. To do this it uses the MyBase.Paint event. To make it work the ProgressBar is made invisible and the UserControl is 'painted' with an image of the ProgressBar and then the text is painted on top. The UserControl has a Value property that is passed through to the ProgressBar.Value property.
I use this UserControl in two places, on a Splash form (not a standard Splash Screen) and also on the main form of the application. It works on the Splash form but not on the main form - by work I mean that changes to the ProgressBar.Value property cause the ProgressBar to show its progress. The cause appears to be that in the Splash form case the MyBase.Paint event is called as a consequence of calling Me.Refresh in the Set procedure of the UserControl.Value property, in the main form case it isn't,
i.e. Me.Refresh isn't causing MyBase.Paint to run.
The main form has two BackgroundWorker components. The first gets called (RunWorkerAsync) from Form_Load after the Splash form has been shown. The BackgroundWorker.ProgressChanged event updates the Value property of the UserControl and it works exactly as intended. The second gets called as a result of a user starting an operation and again the BackgroundWorker.ProgressChanged event updates the Value property of the UserControl but MyBase.Paint doesn't run so the ProgressBar remains resolutely static.
Any ideas why it won't respond to Me.Refresh in one case but does in the other? Happy to make any of the code avaialble but didn't want to fllod the first post with reams of it. Here's what I think are the most relevant code sections. First the UserControl

OK so after a week of aggravating, hair pulling, disaster of trying to figure out what should be simple tasks but beat me down! Ok so I wanted to create a application that would, somewhat manage the users own collection of video games (Lame i know ) you add your games to a listview item, with an image and some sub items, viewing details, using a textbox to search your games... etc i hope you get it
Ok so what i cannot figure out, or find by combing the internet! is how to save all new items the user adds... And including: the item, all the sub items and the picture thats associated with the item.! Instead of posting the code, i posted the application Source code itself here:Source Code , I also started a project here: Codeplex
Later i eventually was thinkin of ading a "wish list" feature where you could add the games you want to get later and also tag it with a release date so when the date comes up, it will let you know, maybe through some alarming way or textbox somehwere... IF you guys want to make it better or fix it! go ahead, i just want this app to save upon EXIT or directing me in the right direction would be VERY VERY much appreciated!
I changed my Username on my computer from i.e. "xxxxxx x xxxxx" to "Dennis"
VB 2008 during a compile gave me the following error: Error reading icon 'C:Usersxxxxxx x xxxxxAppDataRoamingMicrosoftVBExpress9.0VSProjectApplication.ico' -- The system cannot find the path specified.
The file "VSProjectApplication.ico" is in 'C:UsersDennisAppDataRoamingMicrosoftVBExpress9.0'
Somewhere in the VB2008 "configuration" files I believe that I need to manually change the old path to the new path.
I found the old path in the ".suo" file. The ".suo" file is not a text file. How can I edit the .suo file, save it so that it will work?
on my Form I have a DataViewGrid and some textboxes with a save button (they are filled with additional data of the selected row).Save is disabled first, when I change something in the textboxes the save button is enabled.When the user changes a gow in the grid, I want to ask before changing the grid row, if he wants to save (if the button is enabled).I am using RowEnter but this is too late, then the selected row already changed (and my textboxes already got new data)...What event can I use to ask if I should save stuff before the user changes a row?Something like BeforeRowChanging with a chance to cancel changing the row?

View 1 RepliesI recently had to format my PC, So I moved my project files and build files to my External Hard Drive, and continued to work on my project..I started to receive emails saying that the application is saying "Cannot download the application. The application is missing required files. Contact application vendor for assistance." After clicked view details, I found this:+ Downloading file:///C:/Users/myuser/Downloads/Browser.application did not succeed.I was confused, the .application file is not in Downloads, its supposed to download it from my website. And if I were to open my project on a computer with it already installed, it won't check for updates - it opens really quick without the "Viewing Application Requirments" window.

View 10 RepliesI have an application developed in VB 6.0 and VBA that uses latest Office 32 bit version. But since this application is 32 bit, it does not run on systems where 64 bit Office versions are installed. What is the best strategy I have to adopt to port this application to 64 bit. We have a mandate to use VB.NET and minimal (as much as possible) code modification from VB/VBA to .NET 64 bit. Please suggest the best option I can use so that I can leverage all best practices for this porting.
