It seems like in order to use "TextFieldParser " you need to include the path of the file to be parsed. Is it possible to use OpenFileDialog1 and then choose a file? I keep getting error messages.

I am running a piece of code which takes 3 secs to process and it is triggered by the clicking on the OK button on the OpenFileDialog1 box.
Everything works fine except the OpenFileDialog1 remains visible during this 3 second time period and I would prefer it to immediately hide once I click on the OK button.
I have inserted me.refresh in various locations without success but I believe this is acting on the form itself.
Any thoughts on ow to allow the box to close / refresh before the processing

I am having a problem with the AutoUpgradeEnabled property on OpenFileDialog1 and SaveFileDialog1. When set to True and I call it, it works fine, but it takes 2-5 seconds to return the filename I just selected with the dialog. The Dialog box changes to a larger box than when it's set to False. If I leave the property set to False, everything works normally and the selected filename pops up immediately. What does this AutoUpgradeEnabled property mean and why does it take so long to work? (I experienced this problem with VS2005 and VS2010)

Why would a .sln solution file open and appear empty in Microsoft Visual Basic 2010 Express - i.e. no windows showing projects and code files etc.When I inspect the file in a text editor, it contains references to vbproj files (which are present) which indicate that it should not appear as empty.No error messages are reported when the file is opened.

I've noticed that when you click on a web page in Windows Explorer, or open a file in general, and the default application to open it is internet explorer, ie opens and opens the file. However, when I tried this on my Web Browser it opened, but ignored the file and went on its usual routine. How can I get my Web Browser to open and open the file that was clicked on in explorer?

I saved a file with the extension .doc. I use the RichText to write and save the text. I did not set any encoding type when I saved it. When I tried to open the file in the Richtextbox again, I got all the formatting characters in the RTF file. How do I correct this? How do I open and re-open a .doc file in the Rich Text box control without the formatting showing up in the box with the document contents?

I am using VB 2008
I created a simple form which has two tableadapters to a Access database. On the form I have a combobox that uses the Category TableAdapter and it populates on load fine. the other control is a DataGridView1 which is popluated by the Message Table Adapter based on which Category is selected. It does NOT populate on LOAD and thats my problem.
So the result I'm looking for is when you run the app and my first form loads it
A. Chooses the frist Category in the list (and it does that fine)
B. Populates the DataGridView1 based on the first Category (this is my problem)
The DataGridView1 does Populate after I re-select the Category in the combobox1.
Here is my code below.
