• Visual C++ Problem with Active-x Control...

  Hi All, I am having this acgivex control which scans cards and stuffs like that, the initial problem was that the active-x control shipped with the product had a 3-4 seconds pause after scanning and populating the values onto my HTML controls.

• .NET Development Executing a query against Access and Excel

  Hi, there I wrote a program that reads data from both Excel and Access. But I don't know how to submit a query to both of them. Connection to Excel is made through OleDb in code, and Access connection is made through Database Explorer, in design time. The question is: how can I make reference to these sources Thanks, Flavia Hi, Ok, sorry for the misunderstanding. You meant to have a query statement that uses two different data sources (connections). Sad to say but this is not possible. A more logical way is to manually query your excel table and loop through it and query your access table and store the querried result in a datatable.. cheers, Paul June A. Domag ...Show All

• Visual C# How to find / locate a control on a form?

  Hi, I have a configuration file, which specifies which controls should be disabled based on certain criteria. The only way I know of getting a refernce to the control in the form is to recursively go through every control. Unfortunately, this is not a viable solution for me. Does anybody know if there is another way to access the control I need based on its Name property, or any other property Any outside of the box solutions are welcome. Thanks a lot. Lidiya As you stated, iteration through all controls is not an option. Perhaps you may find the Controls.Find method useful For example: this.Controls.Find("textBox6", true) ...Show All
