launching multiple forms from one application

Question

I have 4 old upload modules. These upload modules make use of a dll someone written a long time ago. This project is lost and I don't really want do decompile the dll.

I would like to have one upload module where they can select one of these 4 upload modules.

They all have this code in the program.cs:

[STAThread] static void Main() { new APACMiscUM(); }

This class triggers the dll.

namespace ApacMiscUploadModule { class APACMiscUM : UploadModule.UploadModule { public override void applicationStart() { showMessage("Upload Module", Color.Green); Connection = new SqlConnection("X"); } public override void fileSelected() { ... } } }

When the new object is created (APACMiscUM) the dll (UploadModule.UploadModule) creates the interface. How can I activate this form after clicking a button on a new form?

ADDITIONAL INFO:

"when the new object is created" - which object? And which form? And which button? !!!! — noelicus

In the Main function in program.cs. It ceates the object APACMiscUM and this object creates the uploadmodule object — Freddy

Save the object created fromAPACMiscUM. Call object methods, simple enough I guess.

[STAThread] static void Main() { var classObject = new APACMiscUM(); var someReturnTyoe = classObject.SomeMethod(SomeArgument) }

I got the following error: Starting a second message loop on a single thread is not a valid operation. Use Form.ShowDialog instead. Form.ShowDialog doesn't exist or APACMiscUM.ShowDialog also doesn't exist

Copy the upload-modules (APACMiscUM.cs, APACUM.cs, EMEASeiUM.cs and EMEAUM.cs) to a windows form project. Reference the upload-dll. Place four buttons on the form. Create code like this:

 private void button1_Click(object sender, EventArgs e) { new APACMiscUM(); } private void button2_Click(object sender, EventArgs e) { new APACUM(); } private void button3_Click(object sender, EventArgs e) { new EMEASeiUM(); } private void button4_Click(object sender, EventArgs e) { new EMEAUM(); }

It is fairly straightforward.

True but this doens't work unfortunately. You get this error: Starting a second message loop on a single thread is not a valid operation. Use Form.ShowDialog instead. Form.ShowDialog doesn't exist or APACMiscUM.ShowDialog also doesn't exist
