I have a bunch of controls loaded into the same row/column in a TableLayoutPanel. I only have one at controls visible property set to TRUE at a given time. I want to be able to loop through the controls that specific row/column position in the TableLayoutPanel and test for a condition (control type) and then set this control's property to TRUE and all others to FALSE. Bascially I am turning controls on/off.
I know can loop through an entire TableLayoutPanel like this:
For each control in TableLAyoutPanel.Controls
Next
How do I restrict this loop to a specific row/column in the TableLayoutPAnel? Can you qualify where specifically you want to look in the container control?

I am trying to input specific information on a form. I have created an sql statement from a table that will out put 18 rows of data. I have opened a recordset and instituted a do until loop. I need for the program to look at each row and if the Standard Score = the value of a field I have on the form it takes the value of the other three columns in updates it on the form. I have created the code and it works for upto 3 (Do Until loops)records, but when I try to add a 4th in the SQL statement and put in another do loop my computer runs it but it acts as if it freezes up.

View 1 RepliesIs it possible to define my list of strings like in 'good old' VB60, to use only on ebyte of memory for each character? .NET always seems to store any string as unicode, which doubles the required memory. The case is that I have a huge list of strings, all of the same size. It is about 50.000.000 items, 12 characters each. You can imagine I am running out of memory in no time. I tried converting them to arrays-of-bytes but in that case I loose the possibility to perform a "LIKE" statement in a FOR-EACH loop to check for a specific item.
