I'm try to use Vista TaskDialog Wrapper and Emulator and I'm getting the following exception:
"Unable to find an entry point named 'TaskDialogIndirect' in DLL 'ComCtl32'."
...in a simple Console application:
class Program
{
[STAThread]
static void Main(string[] args)
{
System.Threading.Thread.CurrentThread.CurrentUICulture = System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US");
PSTaskDialog.cTaskDialog.MessageBox(
"MessageBox Title",
"The main instruction text for the message box is shown here.",
"The content text for the message box is shown here and the text willautomatically wrap as needed.",
PSTaskDialog.eTaskDialogButtons.YesNo,
PSTaskDialog.eSysIcons.Information
);
}
}
What am I doing wrong?
UPDATE:
Actually, I'm working on an Excel plugin using excel-dna. How can I control what dll Excel loads?
I haven't been at Office programming in a while, but my guess is that Excel loads both versions of comctl32, so you may need to use the Activation Context API to direct your code to the version that includes TaskDialog. Some ideas for fixing the problem (not solutions as such):
For test purposes, make a temporary enumeration of all modules in the active process - just to check if 6.10 is actually loaded (see below for a simple example of such an enumeration, albeit with a different intent).
Use the Activation Context API to get to the right version. Example of use from C# (for enabling themes by way of comctl32 6.0) here.
Alternatively (I never actually got this to work reliably in a WPF application I worked on), make a dialog abstraction class, which falls back to MessageDlg depending on the version available to you. There may be better ways of doing the check, but...:
