Lets start first to make the application visible. Add a property ‘Visible’ as a VARIANT_BOOL. The code should look like this: //———————————————– // get & put_Visible //———————————————– // STDMETHODIMP CAutoATLApp::get_Visible(VARIANT_BOOL *pVal) { METHOD_PROLOGUE_ATL CWnd* pMainWnd = AfxGetMainWnd(); ASSERT(pMainWnd); *pVal = pMainWnd->IsWindowVisible(); return S_OK; } STDMETHODIMP CAutoATLApp::put_Visible(VARIANT_BOOL newVal) { METHOD_PROLOGUE_ATL CWnd* pMainWnd = AfxGetMainWnd(); ASSERT(pMainWnd); pMainWnd->ShowWindow(SW_SHOW); […]

Lesson 7: Data Viewer The moment you have been waiting for, we finally will make a useful application. If you have just skipped the last 6 lessons, then you will probably be able to follow along, but you may not really understand what you are doing. (But since you are the type of person that […]

Making a window visible always even if it’s not the active window is very easy all you have to do is to enable “system modal” style in the window properties. But making a Dialog, SDI/MDI base application visible always at runtime requires more than just enabling some properties. This article is for developers who want […]

Lesson 6: SDI and MDI Applications We are getting to some advanced stuff now. In this lesson I am not going to go in depth at all. I will just give you a flavor of the structure of a SDI (single document interface) and a MDI (multiple document interface) application. In the last lesson we […]

Environment: Visual C++ 5 & 6 Overview When I attempted to use the various toogleheader macros freely availabe in the open source space, Developer Studio would continually crash for such simple things as the file not existing! I think this is a result of a bug in the scripting engine, when you try to open […]

Lesson 5: Dialog-Based Applications We won’t build a dialog application just yet, but I will tell you enough here so that you get the picture of what’s going on in dialog applications. Dialog apps are the simplest apps in my opinion. In the IDE, go to File, New, Projects, MFC AppWizard(exe), and type in a […]

Lesson 4: MFC Basics Are you ready to start programming? No you are not. You don’t want me to teach you a stupid ‘hello world’ application, do you? If you want to make the most of Visual C++ you have to use Microsoft Foundation Classes (MFC). These classes are great because they wrap all of […]

One of the problems you may find while developing a big project is the class renaming. For example I begin using an object of a class CConfig. Then a few moments later I decide to change the class name from ‘CConfig’ to a more specific name ‘CInterfaceConfiguration’. It’s easy but the filenames remain unchanged. You […]

Brief Overview kPad, a lightweight text editor loosely based on the MTPad sample from the Microsoft SDK (12/1/99) allows you to read and manipulate RTF and TXT files using a RichEdit control. However, kPad’s main focus is as an example of what you can do using the WTL. Features Sheets control Find and Replace custom […]

Environment: Windows 2000, Visual C++ 6 SP3 Windows 2000 introduces many new great features for us system programmers. Perhaps the best of these features is Microsoft’s implementation of WBEM. WBEM is an industry wide initiative to make system management a more cross platform endevour. WBEM is incorporated deeply into Windows 2000, and is the facility […]

Lesson 3: Visual C++ IDE and Workspaces Windows programming is tricky stuff. Don’t let anyone fool you. But microsoft has blessed us with their IDE called Developer’s Studio. It will handle all the compiling and linking, provides help, fills in tons of code for you, and gives you that ‘visual’ designing environment to make cute […]

The code here is also a great example of how to use Windows API for handling COM/DCOM objects. Method Descriptions and Definitions Main function : getInterfacePointer Prototype int getInterfacePointer(IUnknown **ppInterface, void *comObjectInfo, void *interfaceObjectInfo, int flags = SKDCOM_COMINFO_NAME | SKDCOM_INTERFACEINFO_NAME, void *computerName = NULL, COAUTHINFO *pAuthInfo = NULL); Parameters ppInterface [out] Pointer for interface pointer […]
