I am trying to create a code where I placed sets of numbers in an array.I'll use a masktextbox to have the user enter the numbers to match what's in the array. If the user enters the number, ex: social, and the data is correct (matches the numbers in the array), something happens if the number entered in the masktextbox does not match any of the number sets in an array then another thing happens.The masktextbox so far only validates format and gets number only, however, I want the number entered to match whats in the array.
View 1 Repliesi wanted to link options selected from Comb box A (general) to specific options in combo box B (specific).

How do I prevent this from happening or if I can't prevent it, how do I work around it? The following is the code used.

View 3 RepliesI have a form with 8 combo boxes and would like to disble certain combo boxes, depending on what was selected in another combo box. The reason is so the user will not have a blank return on a query. The first form I created like this worked great, no issues. This form only allows one combo box (Number_of_Lightheads) to disable any others. Below is the code I have for this Form. why the other combo boxes will not disable the ones that are called out in the code?

View 11 RepliesI was wondering if there is a way to include / 'run' C++ code within VB.net I think I read somewhere about turning the C++ Code into a library and can access it that way, but not 100% sure if I did in fact read that right or if I'm dreaming things up. Basically, I want to design a basic UI, ie just a button or 2, and when the button is clicked I'd like it to use the C++ Code.

I thought I could check Err.Number once I was out of the Try/Catch block but that doesn't work because apparently Err.Number exists within the Catch block after an exception is caught, but outside of the Catch block Err.Number is zero again. How can I do what im trying to do? Im about to NOT use try/catch and resort to On Error Resume Next (aaahhhh the days when things were simple and just worked)
I have a solution, Winforms, mainly composed from VB.NET projects (Wiforms, Constrols and business classes).
How, I added to it a WPF project, but wrote it in C#. Actually, every time I make a modification in the WPF C# project, I need to (re)build the C#WPF project. Is there a option to make it work like other (VB.NET) projects (accept and "see" the changes without rebuilding the C# project)?
An example:When I reference project "R.VB" in project "M.VB", I add a method "DoTest" in the "R.VB" and use that method in "M.VB" without compile errors.
If I add "DoTest" in the C# WPF Control and try to use it in "M.VB" project, I recieve a compile error "DoTest" is not a member od "R.C#Class".
I have two projects, one written with vb.net and one with c#,I would like to use the vb.net one more as a Class and make the c# project the 'main' one.I have already read that In order to do that I need to compile the vb.net project as a dll and import that dll into the C# project.I am having hard times making it work.Does anyone know how do I import the dll and use the functions that are implemented in the dll?
