I get the following error when trying to compile the simplest prpgram. Error 1 Class 'CLSID_CorSymWriter' could not be created: System Error &H80040154& After looking at other stuff on the net I removed VB 2010, VB 2008, any C or C++ runtimes and any .NET Framework programs I could find, and then re-installed VB 2010, but the problem still persists.

This error first appear to occur randomly. Steps to recreate:Open Visual Studio and load a solution (some files automatically opened) - this is when the problem occurs Close all open files Restart visual studio and load solution (no issues)Open Exactly the same files again, restart visual studio and load solution so files open automatically (problem occurs!)
However, when trying to narrow it down to a single file (that is automatically opened when the solution is loaded), I couldn't reproduce the problem. Now with all the files open again the problem doesn't occur!!! So it looks like it is fixed - though this happened before and eventually the issue came back.
I think it is to do with one of the user controls with DevExpress controls on it - when the error occurs, the designer displays the error. Though I can't reproduce it at the moment to confirm that.
I have a VB 2005 WinForms Project which is giving what I think is a false error.On the Designer screen for the main form (which normally displays the form layout etc.) I get:One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes.'. ctor' is not a valid identifier.

When I try to build a project, vb hangs and displays this message in the notification area
Microsoft Visual Basic Express 2010 is Busy. I have to end up using Task Manager to end the process. I have been using VB Express for about a year and have never had this problem. i have tried to re-install VB 2010 express, no joy. I even built a Hello World app, still no joy. This is really stopping all my VB work.
I used the following code(with bug):
Code:
For n = 0 To 100
If saveLine(n).Substring(0, 8) = "heading:" Then
cboSelect.Items.Add(saveLine(n).Substring(8))
End If
Next n
The For loop only ran 5 times. It turned out that saveline(5) was shorter then 8 characters, so I changed the code which solved the problem:
Code:
For n = 0 To 100
If saveLine(n).Length > 8 Then

VB 2010 neatly exits the for loop when the bug occurs. In this case it was easy for me to pick up the bug, because the combo box was not properly populated. What if it was not obvious that the for loop did not complete? It is quite scary to think that bugs like this are not displayed at run time.
this is my very first posting and I must say I am desperate. I have a VB assignment due in 2 days and I am so lost. I have written a code to draw some graphic, just a basic house, tree, sun etc. I have also written a code to magnify said graphics which were all the specifications of my Assignment 1 part A. Now for Part B I am being asked to extend my program so that: A - My graphic can be drawn using different colour schemes designed by me but chosen by the user B - My graphic or an appropriate part of it can be animated around the picture box if the user chooses to do so. C - Error checking is included.

View 3 RepliesThe Form Designer in the IDE is no longer working properly. When I create a new project, the Form Designer will work, but after I save it and close the IDE and reopen the next day the Form Designer no longer shows the form and instead says "To prevent possible data loss before loading the designer, the following errors must be resolved: An Error occurred while parsing EntityName.Line 2, position 62" If I click ignore and continue, then it just displays a blank form with no controls. The problem appears to have started after I unistalled and reinstalled VB2008 Express.

For those who still have lots of legacy code as I do in .NET 1.1, has anyone found a solution for this issue[url]...
The directory given in the command line will not exist, which makes sense given the error message. The problematic part is that everything works with a full rebuild. Since the "work around" is so easy, Microsoft of course is not going to fix the problem for .net 1.1.
To everyone who pre-emptively suggests an upgrade to .net 2.0+, that is not an acceptable solution, due to time limits and resources. To those who say that is not an acceptable excuse, go find another thread, not every company is perfect.
