View 4 RepliesThe problem I have is that many times, the dataset that this control is bound to is empty. Therefore, the user continuously gets an error saying that one or more fields is missing. When I debug the code, I can see the code in the class loop through all of the radio button controls on the form. Since none of them match the field from the database, the code throws the error. I assume the code expects a match.
Should I modify the class to handle the case when there is a DBNull value? If so, what would be the best method? Or should I approach this situation in a completely different manner?

View 1 RepliesIn my project I would like to call an exe so that exe pop up will come with a Login Screen with 2 buttons Login and Cancel.In those 2 buttons, login button is focussed default. Now my application should invoke the Login button automatically. Means there won't be Pressing ENTER KEY or Mouse Button Etc. Just after the Login Screen, there is a 2nd Screen that has 5 different Radio buttons, the 1st Radio button is always the default. So I also want to click this radio button automatically without using the keyboard or the mouse. y intention is that, the application should do that automatically.
I have tried with getting the handle of the focused Button by GetFocus method and tried to send that handle to the application by SendMessage and PostMessage. But it's not working.So can any body give some suggestion regarding this?
User will use a button1.click to open a filedialog to locate the file they needed. after which, the name of the file will appear on a textbox. Button2 is an OK button to write the filename into a txt file. Button2.click will work with the 3 radio buttons - meaning when Radio Button 1 is true and Button2.click is clicked, the filename will be saved asFile1.txt.if Radio Button 2 is true and Button2.click is clicked, the filename will be saved as File2.txt. Likewise to Radio Button 3

I am using TextFieldParser to Read a Tab Delimited Text DataFile. The problem I have is that some times the data file (3rd party provided) contains an extra Tab which therefore creates an extra column. I need to remove this unnecessary column. Some columns will have rows that are empty so I cant just delete the column if it has a blank row, So I think I need to loop through each column and if if every row is blacnk then delete that column.
Here is the code that reads the file, I was going to remove the column from the table called table before I populate the table called dtAll , which is what my program uses
Dim safeFileName As String = IO.Path.GetFileName(Me.OpenFileDialog1.FileName)
