Is there a good example on using C# with vb.net 2008 or above. I am looking for the simplest example. A class library I would be able to write with C# and use from vb.net. Probably a .dll I would imagine.
Could someone recommend some search strings for this forum I can try? I am looking for the shortest simplest example.
I'm having some problems writing a sub. Below are some screen prints I made a on screen keyboard using all labels This app. is for a touch screen. The first pic is the code for all 40 labels using the If Then statement.(Screen print is for Label2 only). Second pic is the Sub I wrote so when you click on anyone of the labels, the labels text appears in the textbox with focus. As you can see the error I keep getting.
View 5 RepliesI got some textboxes that I can't write in, and no it is not because it is enabled = false. It is strange but I click on a textbox, type something but the textbox stays empty.

View 10 RepliesI have a main form with a number (in this case 9) mdichild forms. Some are visible, some not, but they are all very basic. When I write to a textbox in any child form during Main_Load it updates, when I write to a textbox in any child form inside its own _Load it updates. If I write to one from awhere else in code, including a sub in the form's own code, it fails to update.
All the child forms are identical but are distinctly separate forms created before compilation rather then NEW versions of a single form to avoid threading problems.Curiously this code worked once only. No edits were made and when re-ran failed after stopping it if found all the controls in some of the forms were invisibe in developer mode, restarted VS but still not there. Run app and at runtime there they were!!! Also all locked textboxes still accepting input.

I have been at VB.NET for a very short while now (about 1 month) and I can say without a doubt my knowledge of VB has continued to amplify from the information posted in these forums.Along with my first post I also have a question about setting an icon for my application .exe file.I have read that I need to go to Project > properties then on the Application tab there is a section to change the icon from the default to something else. However when I do this and choose the icon that I want, I get an error when I use the debug to run my application.It says "Unable to write to output file C:/... the specified image file did not contain a resource section".

I have a form that is first displayed as 425 x 66. When you press a button, the form expands to 425 x 398 and a message appears (a label prooperty) with the text: Processing Files. When the files are finished prosessing, a listbox appears and summarizes which records were added to the database.
The label begins as Not Visible. After I change the size of the form, I change the label property to Visible.
This used to work, but now, for some reason, the text simply doesn't appear.
I tried changing the lblproperty to Visible at startup but when I do this I get a black bar where my lable should appear.
