View 1 RepliesI am having trouble openning my vb.net projects in vs2005. What happens when i open one is that i get several windows downloading files from the Appdatalocal emp folder. It says "do you want to open or save this file?. the file name is several random charactors with the tmp extension. do not suggest a virus. The tmp files in question are vs 2005 generated files. they contain html data indicating a problem on the form. If i close all the forms in the tabbed code area, and rebuild the project, then all is well. If i don't build the project, then when i open a form up onto the code area, i get a new download message. Anyone ever heard of this? I suspect IE8 but cannot recall if this all started when i installed IE8 or not.

I have an application that can read certain types of files, and I have it working so that if you do "open with" from windows, it automatically starts the application and opens the selected file.
Unfortnately, I cannot get it to work for more than one file.
System.Environment.GetCommandLineArgs() contrains the following:
System.Environment.GetCommandLineArgs(0) = name and path to the .exe
System.Environment.GetCommandLineArgs(1) = name and path to the first file selected to be opened
System.Environment.GetCommandLineArgs().Length is 2 when the user tries to open 1 file, which makes sense since the first argument is the .exe itself and the 2nd is the path to the file, but it does not increase to 3 if the user tries to open 2 files... meaning that System.Environment.GetCommandLineArgs(2) is never populated Here is some sample code that shows the problem: It will recognize no files or 1 file being opened, but if you try to open multiple it will only show the first.

I have many applications that create TLB files which I guess are so that vb2005 can comunicate with the DLL files. Now what I would like to do is have all my TLB files in one folder and have my application point to that folder to use them.The problem I am having is that my EXE will not run unless all the TLB files are in the same folder as the EXE. I do not want this. I want to put some code into my file that sais that the tlb files it needs are located in say: [code] and still have it work. again right now they all have to be in the same folder which is really bugging me.

The problem is that if I save a file I get "myfile.GDL" if I overwrite that I get a new file "myfile.GDL.GDL" ect.the other problem being that the filtering in the windows save/open dialog wont show .GDL files unless I select "all files".

For illustration purposes:

I use the following code to access a VSS item:
Dim sItem As String = "$/MyVssProject/InexistentFile.txt"
Dim oItem As SourceSafeTypeLib.VSSItem = Nothing
Try
[Code]....
The problem I face is when I try to get an instance to a file that doesn't exist in the VSSDB, thus leading to a COMException, which basically wouldn't be of a problem (I would expect). In fact the exception occurs, but instead of proceeding with the catch code, the debug cursor stays on the line "oItem = m_oSourceSafe.VSSItem(sItem)", showing a dialog with title "COMException crossed a native/managed boundary.
From here the execution doesn't proceed, until I change the content of sItem to an existing file.
Why does the exception not get caught, and how can I achieve it?
Environment: VS2010 with .Net 2.0 on WinXP SP3 x86
I have done quite a bit of research on this issue and haven't came up with anything definitive yet. I am having issues with Excel randomly getting ComExceptions while writing out reports. I am using a Visual Basic 2005 (framework 2.0) console application to create these reports. The problem has been difficult to figure out because it occurs in random places while writing out reports so I can't catch the error to see the problem. I have looked through the differing items that it breaks on and there is nothing odd about them that would cause any of these problems.

I think I have 3 options:
load all the images at start up into memory, some images may or may not be used. as I need each image go through all the container files and open the image into memory. create a dictionary of IDs and what file they are in at start up and then get each image as I need it without have to go through all the container files.
