I 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'v got 3 functions that I'd like to combine into 1. There is only one line in each function that changes. can think of a few ways off the top of my head, but not sure which is "the best", or "proper way" to accomplish this.
Private Function CheckQuads(ByVal QuadNumber As Integer) As Boolean
Dim intArray(3) As Integer
Dim x As Integer = 0

I need to combine an if/then/else with a try/catch and I can't seem to make it work. Basically I need this:
Try
code that might bomb
Catch ex As Exception
[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?

View 3 RepliesHow do I combine richtextboxes? Currently, I am directly saving rich text to a RTB with ".rtf" and I would like to append the rich text information to that box from another RTB. Something like: RTB.rtf &= newrichbox.rtf do not throw any flags but also does not work. What I am ultimately trying to do is save multiple richtextboxes to a single RTF file. I was trying to do it by combining them all into one RTB and using ".savefile()" or is there a better way? Maybe appending them to the file one RTB at a time?
What I'm doing is generating a report, so I have built generic rich text templates that go into multiple RTBs that will create the form sections and I have left placeholders for the data I am adding, so I do replaces on the placeholders to insert the data. However, there are a couple dozen different possible formats for the report based on user options, so I built each section into its own RTB so I can just write out the relevant sections when it comes time to generate the file.
I'm trying to combine two datasets, each with 1 datatable and each having the same schemas. Datatable 1 would have a list of records. Datatable two may, or may no, have some or all of the records from table 1 plus more records. I would like to remove all the records from table 2 that are present in table 1.
This is what I got so far:
For Each table1 As DataTable In ds.Tables
For Each row1 As DataRow In ds.Tables(0).Rows
ds.Tables(0).PrimaryKey = New DataColumn() {ds.Tables(0).Columns(0)} 'Where 0 is the index of the column that's your key
row2 = ds2.Tables(0).Rows.Find(row1("ID"))
'if its found, delete it

View 13 RepliesI have three arraylists (datasets and subsets) that I need to combine into one arrraylist so I can databind it to a repeater control and then present data to the user. As far as I know, you can only bind the repeater with one datasource (please correct me if this is wrong) that's why I'm combining these arraylists.Each arraylist has an ID from the database which I can use as a datakey to keep the data aligned. How do I combine these lists?
