Hi,

the following C++ code works only in exe. By deploying as DLL it fails on expanding a item:

cpp code

// Fill Tree

	for(int i=0;i<10;i++) {
		TIWCGJQDynaTreeNode *newitem = IWCGJQDynaTree1->Nodes->Add();
		newitem->Title = "Main";

		TIWCGBrowserParam *parm1 = IWCGJQDynaTree1->JQDynaTreeOptions->OnExpand->BrowserParams->Add();
		parm1->ServerName        = "ex_" + newitem->UniqueName;
		parm1->BrowserScript     = newitem->jsNodeCommand(dtnIsExpanded);

		for(int j=0;j<10;j++) {
			TIWCGJQDynaTreeNode *subitem = newitem->Children->Add();
			subitem->Title = "Child";

			TIWCGBrowserParam *parm2 = IWCGJQDynaTree1->JQDynaTreeOptions->OnExpand->BrowserParams->Add();
			parm2->ServerName        = "ex_" + subitem->UniqueName;
			parm2->BrowserScript     = subitem->jsNodeCommand(dtnIsExpanded);

			for(int k=0;k<10;k++) {
				TIWCGJQDynaTreeNode *subsubitem = subitem->Children->Add();
				subsubitem->Title = "SubChild";
                        }
		}
	}

What can I do?

Hi Frank

Putting the browser in debug, in can see this in browser console

POST http://www.cmportal01.de/cgi-bin/Tree.d ... GJQDYNATRE…ATREE1_9_7=false&ex_IWCGJQDYNATREE1_9_8=false&ex_IWCGJQDYNATREE1_9_9=false 404 (Not Found)

But it's a strange behaviour for a 404 error, please can you post any code related to tree links?

I take the opportunity to adivse, also for future reading, how to debug an ISAPI dll, you should be able to debug the same way in C++

In delphi is run

- make sure delphi runs as admin
- start the web app / site
- In IDE menu, Run + Attach to Process, and select w3wp.exe
- a cpu window appears, hit F9, and you should be able to see some breakpoints.

i hope it helps

Hi,

there is no other code in this little project. It's specially developed to show you this behavoir.

BTW: if the indexes only run to 5 instead of 10 it will also run as DLL.

What can I do?

best regards

Hello

Send us the little project please. t.i.a.

you have email at Support at cgdevtools dot com

Hi Frank,

First, you don't need add the browser parameter for each node, it will increase the request url to Expand event.
Remove this part.

You must use the browser parameter (dtnIsExpanded), when you need it, e.g: onclick of button.


Also, you need configure IIS:

• Increase query size limit:
  
  

  Code: Select all

  configuration/system.webServer/security/requestFiltering/requestLimits@maxQueryString to 32768


  
  
• Increase upload limit:
  
  

  Code: Select all

  appcmd.exe set config "SiteName" /section:system.webServer/serverRuntime /uploadReadAheadSize:"1048576" /commit:apphost

Thanks.

Best Regards.

Thank you - it runs
