| | [size=2][color=#0000ff]Use the shellExecute function. There's plenty of documentation on it in the MSDN. I copied this from a piece of one of my functions which wouldn't actually open notepad, it opens from a filename, in which case if it was a file with a *.txt extension it would open up … |

| | this is a wrapper around the AnimateWindow API. this allows random animations in a dialog. I just call it in the dialog's OnInitDialog() handler.

| | I've never been to school for programming (other than some very preliminary VB5 classes in a Data Processing course). The company I now work for taught me what I needed to know about VB6 and database design. I then taught myself C++ and some minor DirectX programming and think that …  |

| | add a webbrowser control to your program and associate a variable with it, then in OnInitDialog() put this: [CODE] m_ctlBrowser.Navigate("YOURURL",NULL,NULL,NULL,NULL); [/CODE] or if you just want it to execute without a dialog I think you can use the ShellExecute() function and send it a string for the URL as a … |
 | > well, i have seen the page but i could not find anything useful, there were something about reading function keys but nothing about reading reading multiple keys or different keystates. try GetAsyncKeyState() to get the key you want.

| | Polymorphism is what makes using inheritance so powerful ( in my opinion). Here's a quick example of it using objects. This example uses 3 classes: CCar, and CSportsCar and CLuxuryCar which are derived from CCar. [code]class CCar { //constructors and other stuff... virtual CString GetType() { return "Car";) } ; …  |
| | Re: Visual C++ C++ is the object-oriented version of C. Objects are a lot easier to work with, and with inheritance and polymorphism, eventually you can reuse just about any class (base for an object) over and over again. The 'Visual' part comes in with Microsoft's interface for easily building GUI applications, which …  |

| | if you're not using a database, I think the best route to go would be to add the items to a drop-down list combobox, with an itemdata being their price for each item. Each time an item in the combo is clicked the itemdata (price) would be displayed in the … |

| | Is there a way in VB to use a '#define' macro something like in c++? In C++ I can do this: #define CHECKPTR if(!ptr) AfxMessageBox("Pointer is null"); then everywhere I wanted to do that check, (of course the pointer would always have to be named 'ptr'), I could just write … |
