Need hwnd for active document

Question

I'm doing some automation with Windows forms, C# and the SDK. I use code like this to open a document in Acrobat 8.x (full version, not the reader)
string szPdfPathConst = "myfile.pdf";
avDoc =
new AcroAVDocClass();success = avDoc.Open(szPdfPathConst,
Now I want to close the document and open a different one in the same reader window using OpenInWindowEx. How do I get the hWnd handle?

After much experimentation, this code works, but it does not work. It reports sucess and I can get a page count for each document I open, but it does not actually open the document in the active Adobe Professional Window. I have been able to fiddle with this and at least get a document to come up in a new professional window (by just executing avDoc.Open each time) but the user has to close the old one manually.
Guess I'll have to try some other method of getting this to do what I want which is to be able to display various pdf documents from a windows forms application in a window on a computer with adobe professional installed. I didn't think it would be this hard...
private void StartAcrobatIac(){
// mApp, avDoc and pdDoc objects are declared outside of this method
// so I can manipulate the document elsewhere, here is the code used
// CAcroApp mApp;
// mApp = new AcroAppClass();
// CAcroPDDoc pdDoc;
// CAcroAVDoc avDoc;
//user selected file name.
string szPdfPathConst = textBoxFileName.Text;
//variables
string szName;
int iNum = 0;
bool success;mApp.Show();
// will add error check
System.Diagnostics.
Process[] processes = System.Diagnostics.Process.GetProcessesByName("Acrobat");
// close the old file if open
if (avDoc != null){
mApp.CloseAllDocs();
//open the PDF
success = avDoc.OpenInWindowEx(szPdfPathConst, (
int)processes[0].Handle, (int)AVOpenParams.AV_PAGE_VIEW, 0, 0, 0, 0, 0, 0, 0);}
else
avDoc =
new AcroAVDocClass();
// try to use OpenInWindowEx here will fail.
success = avDoc.Open(szPdfPathConst,
"Adobe Acrobat Professional");}
if (success){
//set the pdDoc object and get some data
pdDoc = (
CAcroPDDoc)avDoc.GetPDDoc();iNum = pdDoc.GetNumPages();
szName = pdDoc.GetFileName();
//try to Show Acrobat doc again.. window is still blank with no document loaded
mApp.Show();
else
MessageBox.Show("document did not open");}
