Make certain that AtlAxWinInit has been referred to as.

AtlAxWinInit()

Q23. What Is Class Description Of Caxwindow?

Wraps an "AtlAxWin80" window, presenting methods for developing the window, creating a manipulate and/or attaching a manipulate to the window, and retrieving interface hints at the host object.

Q24. What Are The Reasons An Atl Server Might Fail To Register?

The following are the top 3 motives an ATL server may fail to sign up:

You built your venture with _WIN32_WINNT=0x400 (the default), and also you are not jogging the ATL server below Windows NT four.Zero otherwise you do no longer have an uptodate model of Oleaut32.Dll. To solve this hassle, run "DUMPBIN /EXPORTS OLEAUT32.DLL" and look for UnregisterTypelib. If it is not there, then your server can't run. Remove this #define assertion from Stdafx.H in case you want to run the ATL server below Windows 95 or older variations of Windows NT. Alternatively, you could use LoadLibrary and GetProcAddress so you can run optimally underneath each Windows 95 and Windows NT four.@The Oleaut32.Dll that ships with the Internet Explorer three.X is uptodate.

You built your assignment as MinSize and Atl.Dll is not properly hooked up on the machine. The accurate version of Atl.Dll ought to be copied and registered through Regsvr3@There are Windows NT and Windows 95 variations of Atl.Dll. The Windows ninety five model runs below Windows NT. However, since it does now not use the UNICODE APIs, it's far slightly much less efficient. Unless you build your project as MinDependency, you may want to install the right model of Atl.Dll and run Regsvr32 on it prior to installing your server.

You constructed your task as UNICODE, and you cannot run it under Windows nine@

The following are the stairs to troubleshoot:

For a DLL server, run Regsvr32 within the debugger. Open the Project Settings conversation container and click on the Debug tab. In the Executable for debug session textual content container, enter the overall course to Regsvr32.Exe, along with C:SharedideBinRegsvr32.Exe. In the Program arguments text field, specify the full direction on your DLL, which includes C:MyprojectsMyFolderDebugMyFile.Dll. Set a breakpoint at DllRegisterServer and begin stepping.

For an EXE server, run it within the debugger and specify /REGSVR as its commandline argument.

Q25. What Is Function Description Of Atlaxcreatecontrol? (wer.Hypertext Preprocessor?

Creates a number item, connects it to the provided window, then masses a manage.

Q26. What Is The Information That Srfs Typically Contain?

SRF documents incorporate HTML and script tags denoted by the  commencing and  closing braces.

A unmarried SRF report can also call code from a number of application DLLs and a unmarried utility DLL may serve some of SRF documents.

Following is a listing of tags used within the SRF:

The codepage tag within an SRF is used when the SRF is parsed.

The comment tag does no longer rendered at the client Web browser.

The handler tag specifies the call of the Web application DLL and the call of the request handler. There can best be one handler tag in line with SRF.

The consist of tag inserts the rendered content of another SRF on the present day position of the SRF that makes use of it.

The locale tag means that any content rendered after that factor inside the record need to aid the locale this is specified.

The substitute tag is a customized tag that is replaced with content from the request handler within your Web utility DLL.

The subhandler tag defines a further request handler. Unlike the handler tag, there can be multiple subhandler tags within an SRF.

Q27. What Is Function Description Of Atlaxcreatecontrollicex?

Creates a certified ActiveX control, initializes it, and hosts it inside the precise window, just like AtlAxCreateControlLic.

Q28. Explain The Atl Server Architecture?

The Web server gets requests from the purchaser and passes them on to the ISAPI extension DLL when the request is for a record extension dealt with by way of that DLL.

The ISAPI extension DLL receives requests from IIS and passes them on to the perfect Web application DLL.

Web software DLLs offer utility-particular functionality for managing requests and generating responses.

Server response documents are textual content files that include the static parts of a response and unique tags describing wherein request handler techniques may be referred to as to generate the dynamic elements of the reaction.

Q29. What Is Function Description Of Atlaxcreatecontrolex?

Creates a number object, connects it to the supplied window, then hundreds a manipulate (also lets in occasion sinks to be installation).

Q30. What Is "atlaxwin80"?

"AtlAxWin80" is the call of a window elegance that helps offer ATL's controlhosting functionality. When you create an instance of this elegance, the window manner will mechanically use the controlhosting API to create a number object related to the window and load it with the control that you specify as the name of the window.

Q31. What Is Class Description Of Caxdialogimpl?

Acts as a base elegance for conversation instructions primarily based on a conversation aid. Such dialogs can include ActiveX controls.
