I've downloaded the MSDN "101 VB Samples" from the MS site and I'm getting an error that reads "The project type is not supported by this installation". I can open the other files that I've tried (about a dozen in other folders), so I'm wondering if it is something specific with the VSTO files, or something about my VB setup.
I thought at first it was a problem with the path where the file is sitting, but even moving it from C:Documents and Settings[my name]My DocumentsMSDN to C: didn't work...Edit: I have also tried opening in notepad and converting the file to UTF-8, changing the File Association from MS Visual Studio version selector to devenv.exe, and running devenv /setup at the command prompt, all with no luck (all these ideas were found through Googling the error message....).

I am trying to build an error handler for my desktop application. The code Is in the class ZipCM.ErrorManager listed below.What I am finding is that the outputted file is not giving me the correct info for the StackTrace.Here is how I am trying to use it:

What is happenning is the .GetFileLineNumber() is getting the line number from 'objErr.Stack = New System.Diagnostics.StackTrace(True)' inside my Try..Catch block. In fact, it's the exact line number that is on. how I can catch the real line number the error is occuring on?

Does anyone know of a solution for writing text to an image using an OTF? I know that GDI+ does not support OTF and that WPF does. I can load the font as a label in WPF, but still do not know how I can write this over an image, such as a watermark would do, and save that image.
I need this in an ASP.net page, so I won't actually be able to use WPF, but I figure that might be a start in building a class my page can import.

I now have SQL Parameters set up and I'm using them to save/delete/add my data. This all works well, except when it's trying to save a combobox to the datatable it appears with the error above.Majority of my comboboxes have datasources, and the valuemembers of these are the actual list items, not the ID's of the list items.I'm not sure why this error could be happening, I'm fairly sure I've connected everything to the binding source correctly; I've checked it a few times.Does anybody know what the cause of this could be? I've looked around a bit and I haven't found much

I'm getting the error "Conversion from type 'DBNull' to type 'Date' is not valid."here's the line generating the error.
dtReady.Value = dSet.Tables("Db").Rows(Inc).Item("Fixed_Date")
I'm using a date/time picker control and sending the db value to it. I know that the value is null, but I don't understand why the Picker can't be blank. Is there a way to let it be blank? Or should I set up a way to check for nulls and assign today's date or something just in case?
how can I solve this error without having to fill all of my fields. Some of the fields in my database are Nulls and some have records.

I have this code working. It sets the Visible property of controlToSecure to False. [Code] However I would like to get rid of hardcoding types of properties. In this case i'm hardcoding Boolean. Instead I would like to define the property type dynamically. I tried it like below but I get an error on line 2 "Type property Type is not defined". I just defined that type on the line before though? Does anyone know why this doesn't work and how i could get it to work? [Code]
View 3 RepliesI am getting the error "Conversion from type 'DataGridViewTextBoxCell' to type 'String' is not valid." When trying to display a cell from DGV in a listbox.I have my variable for the cell reference as follows:
Dim a As Object
a = DataGridView1(4,1)
To insert it in the listbox as follows:
lstLetter.Items.Add(String.Format(a))
I tried:
lstLetter.Items.Add(a)
This will not actually display the entry inside the referenced cell, it shows this in my listbox instead:
DataGridView TextBoxCell { ColumnIndex=4, RowIndex=1 }
how I need to convert this to display.
