Rajesh Varatharajan — Tue, 16 Mar 2021 10:39:14 GMT

My code is as follows:

#include <Mstn\MdlApi\MdlApi.h>
#include <Mstn\cmdlist.r.h>
#include <Mstn\MdlApi\msnativewindow.h>
#include <windows.h>
#include <DgnPlatform\DgnFile.h>
#include <DgnPlatform\DgnFileIO\DgnFileIOApi.h>

extern "C" DLLEXPORT void MdlMain(int argc, WCharCP argv[])
{
HWND hWnd = NULL;
hWnd = (HWND)mdlNativeWindow_getMainHandle(0);

return;

}

I can't able to resolve these build errors.

How to cancel save/auto-save action through API?

Rajesh Varatharajan — Wed, 05 May 2021 16:51:13 GMT

Hi,

I am trying to cancel some actions (ex. File->Save, File->SaveAs, File->print, File->close).

I can able to block other commands in above except File->Save. While blocking save action, the modifications are getting saved.

After MS_DGNAUTOSAVE set to 0, modifications not saved. How to block autosave action through programmatically.

InputFilterReturnValue monitorFunction(Inputq_element* queueElementP) 
{	
	if (queueElementP != NULL)
	{
		if (queueElementP->u.cmd.command == File_Save)
		{
			return INPUT_REJECT;
		}
	}
	return INPUT_ACCEPT;
}

In above code File_Save is commandid of File->Save action.

How to disable menu in MicroStation CE Update15 using XCommands?

Rajesh Varatharajan — Wed, 28 Apr 2021 18:11:35 GMT

Attached sample code snippet. I am getting command name using Xcommand.

In that, there is SetIsEnabled(bool Enabled) API.

How to use this. I am facing compilation error in Visual Studio 2017.

void DisableMenu()
{
	 IXCommandCP cmd_ptr = XCommandManager::GetManager().FindXCommandByIconName(L"About");
	 IXCommand* xcmd = (IXCommand*)cmd_ptr;
	 xcmd->SetIsEnabled(FALSE);
}

Error:

error LNK2019: unresolved external symbol "__declspec(dllimport) public: void __cdecl Bentley::ECN::IUICommand::SetIsEnabled(bool)" (__imp_?SetIsEnabled@IUICommand@ECN@Bentley@@QEAAX_N@Z) referenced in function "void __cdecl DisableMenu(void)" (?DisableMenu@@YAXXZ).

How to implement SetFileSaveFunction callback function?

Rajesh Varatharajan — Thu, 04 Mar 2021 18:48:52 GMT

I develop add-on for MicroStation using CONNECT Edition application with C++.

Using Microstation10.15 update SDK

I would like to get Save event when save triggered.

extern "C" DLLEXPORT void MdlMain(int argc, WCharCP argv[])
{
SystemCallback::SetFileSaveFunction(OnFileSave);
return;
}

void OnFileSave(DgnPlatform::ProcessChangesWhen when, DgnPlatform::DgnFileChanges changesFlag, DgnPlatform::DgnSaveReason reason, double timestamp, DgnFileP pFile)
{
WString Filename = pFile->GetFileName();
if (reason == DgnPlatform::DgnSaveReason::UserInitiated)
{

/// do operations
}

}

OnFileSave function is never called.

How can I make this callback functionality working?

How to Encrypt dgn file using externel dll?

Rajesh Varatharajan — Thu, 04 Mar 2021 18:53:39 GMT

We have our own encrypt mechanism . We would like to implement it when save action triggers.

Also we would like to decrypt it when open action triggers.

We tried with Read and Write API hooking. But its not Succeeded.

Is there any possible way to do it?

Thanks in Advance.
