Re: is this conversion from a char buf to a wchar correct?

I mean, for instance

7305 seconds = 2 hours, 1 minute, 42 seconds

for such a conversion floats are not needed:

int iTotSecs = 7305;
int iHours, iMins, iSecs;
iHours = iTotSecs / 3600;
iMins = (iTotSecs % 3600) / 60;
iSecs = iTotSecs % 60;

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

To eliminate all the warnings a simple cast on the original variable is enough.

Instead of using char memory to variable buf, why don't you simply allocate the memory to wchar!

How to create a Toolbar with Dockin & Floating effect??

I wish to create an editor with a Docked Toolbar, which can be dragged to make it a Floating Toolbar. When user will drag the Floating Toolbar to the Top/Right/Bottom/Left border of the editor, it should be Docked to that border area of the editor.
This phenomenon is too common in various editors we use. How to create this effect in WIN32?? Is there any API or toolbar-property or any standard approch to enable a toolbar to provide this Docking-Floating Effect, sensing the mouse drag??
Can anyone help me out?? Confused | :confused:

Many companies in the world have what is either a real or a virtual monopoly - 2 products that may spring to mind immediately as being subjects of this monopoly are mp3 players & pc operating systems.

Search Engines, however are reasonably abundant. You may have noticed already that even our beloved Code Project has one. If you type "Docking Toolbar win32" into CP's, you'll find two pages of them.

Hi,

I am new to VC++, I have a source code for decryption of video. it uses DirectX technology, Now I want to modify that program. But whenever i going to build it, it gives the following error messege...

fatal error LNK1181: cannot open input file 'C:\DXSDK\Samples\C++\DirectShow\BaseClasses\Debug_Unicode\strmbasd.lib'

I have installed the new version of DirectX on my machine. I tried to search that .lib file on my system, but i am not able to search it.

Possibly you have to install the (latest) DirectX SDK [^].

I have already installed DirectX 9.0 on my system.

DirectX runtime and DirectX SDK (Software Development Kit) are two quite different things.
Are you sure you have the SDK installed?

If you've built it then you now have it. Change your IDE settings to make it aware of the library presence.

Why don't you put the file there (or is it already there)?

yes... i got a solution... there is one solution in C:\DXSDK\Samples\C++\DirectShow\BaseClasses\BaseClasses.sln and build that solution. It generates that library file...

Thanks for the suggestion.
