Is it possible to Check if the Selected Application is a .Net Executeable ?
Like the User opens a OpenFileDialog selects a Executeable and the Program checks if it is coded with the .Net Framework.
In my Windows Form I have a ComboBox that is filled by a Stored Procedure with a list of names. I have the Combobox set for AutoComplete to "Suggest" and From "ListItems". When a user starts to type in and the AutoComplete does not find any matches in the listitems the user can tab out of the ComboBox and leave what they typed in the combobox even though it is not one of the Valid Items. Is there a way to check the Comboxbox to make sure of of the selected Items has been selected?

I know there are work-arounds like using a Select Case, but in my situation, it would make things a lot easier... especially since I won't know exactly what will be entered. I can't force the user to use a combobox or anything like that either, because it is going to be unique code for every situation. If there is no way of doing this, I will figure something else out, but it will require a lot more work.

To explain, say I have TableLayoutPanel1 with 6 radio buttons and I'm doing an error check to make sure that at least one radio button has been selected during a click event.

View 14 RepliesI am trying to filter a dataset using a number different inputs, selected by a number of check boxes. I have all the text base rowfilters working, but I can not make the date filter work unless I hard code the datetime into the code. The database is MS Access and I am using VB2008 to show the data. I would like to be able to use a DateTimePicker to set the filter date (without the time part) Also I would need to remove the time section of the datEnterDate. I cannot change the structure of the database fields. Also the datEnterDate is MM/dd/yyyy, because I'm in England I would like to use the format of dd/MM/yyyy if possible

If the application is running I want a label to say running, but if it isn't running then the label will say closed.
Is there any way to check if my application really has any dependencies?
