Make an ActiveX control work without a form?
- by Earlz
We are using Topaz Signature pads. They provide their APIs in the from of an ActiveX control which is to be put on a Winform control. Well, the way our project will work we do not want to have a form(at least not visible). We just want for the signature ActiveX control to get an image in the background.
static AxSigPlus sig = new AxSIGPLUSLib.AxSigPlus();
public static void Begin()
{
((System.ComponentModel.ISupportInitialize)(sig)).BeginInit();
sig.Name = "sig";
sig.Location = new System.Drawing.Point(0, 0);
sig.Size = new System.Drawing.Size(0, 0);
sig.Enabled = true;
sig.TabletState = 1; //error here
sig.SigCompressionMode = 0;
}
Ok so I get an error at the marked line. The exception is
Exception of type 'System.Windows.Forms.AxHost+InvalidActiveXStateException' was thrown.
What do I do to solve this problem? Would it just be easier to create a new hidden form and put the control on it so it's invisible?
