Jul 27, 2011
Here is my problem-> I have three folders that I need to check if they are empty or not, if one of them is empty, I would like to keep checking the other two, if they are not empty I want to do something and then check the other two, but not all the time all three will be empty or not empty there might be times where one folder has something and the other two not and so on.

Is there a quicker way to check directories? For example I want to check if the folder "A Folders" contains folders from 000A all the way to 999A then lists the folder that are missing? Do you think this is possible?

I want to check inside a dir if any folder exists. Every way I found is to check for a specific folder with name as string. I want something like

I can download the files I want. However, the client has insisted on creating different folders which will contain the version number. So the name of the folders would be something like this: 1.0.1, 1.0.2, 1.0.3, etc.So the files will be contained in the latest version in this case folder 1.0.3. However, how can my web client detect which is the latest one?

I've done an internet search to determine if I can detail if a SQLDataAdapter is empty after running an SQLCommand? My research so far point I can't check if the SQL dataAdapter is empty until I bind it to a dataset/datatable. Ideally would not like to run another SQL command to do a row count to determine if query retruns rows or not. I'm populating a datagridview and would like to alert the user that there is no data to view. What's the most efficent way to check if an SQLDataAdapter is empty?

I have a directory structure as follows;
ad_folder
--folderA
--folderB
--folderC[code]....
at I do not know the number of or the names of the folders, they can be different in different cases, I only have the root path.how I can display folder contents in VB.net and the code worked but couldn't figure out how to create the arrays and display only folders within folders starting with "ad_".
System.IO.DirectoryInfo and System.IO.FileInfo to be used for getting the folders.A literal control can be used to create javascript arrays in ASP.NET. These js arrays can then be used on the client side.

Ive got a Form application in VB.NET.I have many text boxes on one form (about 20). Is there anyway to check them all at once to see if they are empty instead of writing out a massive line of code to check each one individually such as
If txt1.text = "" Or txt2.text="" Then
msgbox("Please fill in all boxes")

I have numerous textboxes which I use to gather data to be placed into an array. But I want to ensure, before I place them to the array,that there is at least one character (letter or number, no space) in each textbox. Seeing as I have about two dozen, it would seem tedious to write an If...Then statement for each of them. And I cannot use a custom textbox class for this. So how can this be done?
