Well, that says you're accessing a name that doesn't exist...but what name are you looking for , and which object are you querying for that name?

Give some detail, man!

From MSDN [^]:

An IDispatch implementation can associate any positive integer ID value with a given name. Zero is reserved for the default, or Value property; -1 is reserved to indicate an unknown name; and other negative values are defined for other purposes. For example, if GetIDsOfNames is called, and the implementation does not recognize one or more of the names, it returns DISP_E_UNKNOWNNAME, and the rgDispId array contains DISPID_UNKNOWN for the entries that correspond to the unknown names. 

How to use ShellStyle.dll in MFC Application

Hi, all

I have a problem during applying custom visual-style to my mfc application.
I want to apply custom style from my ShellStyle.dll file, (not from the default %windir%/shellstyle.dll)

How can I avoid the loading of system file to load my custom file as visual style for my application ?

Thanks in advance,
themilan

Howdy,

I've never seen any mention of specifying a different DLL file to be used by windows to draw your app.
I've seen instances of people using the DrawThemeXXXXXXXX() functions found in uxtheme.h & UxTheme.dll,
though have never been able to see a possible way to load your own theme data.

Reading from "http://msdn.microsoft.com/en-us/library/bb762202(VS.85).aspx": SHGetShellStyleHInstance first attempts to load the version of Shellstyle.dll from the current active visual style. If that is unsuccessful, the version stored in the System32 directory is used.(EDIT: however, that function is deprecated after winXP sp2, so that rules out placing a hook on the function and returning a handle to your own DLL) D'Oh! | :doh:

In short, the only way I've ever themed applications is myself, the hard-way. I.e define all of the bitmaps to be used for your window edges/features/controls etc and then code in the rules that define how they'll be applied (think about the 'behaviour' of WMP11 as it's resized)

Of course, you could just search for one of the many styling libraries out there. There's a great one floating around here somewhere. I think it's called the StyleToolkit by (Darren Sessions)

Adding 2 double datat types

Hello

I have a code where 2 double data types are added,

double = double1 + double2;

I am purposefuly not declaring a variable of type double and writing

what the issue am facing is,

sometime the double2 becomes negative. but i want to ignore the negative and just ad the 2 numbers.

so can i do like,

double = double +- double2;

Let me know.

I believe what you are looking for is abs, that will give you the "absolute value" of whatever you feed it, so if your value is 123, it will give you 123, if it is -321, it will give you 321. Is that what you want?

Ya i want to avoid the negative that sometimes comes up with double2.

so how to do that programmatically?

can you show a sample code?

so does that mean, there is a better way to do that, rather than doing,

double = double1 +- double2; ?????

This:

dipuks wrote:
double = double1 +- double2;

translates into this:
double = double1 + (-1 * double2);
Thus, it will turn your negative double2 to positive BUT it will also turn positive double2 to negative which is i supose not what you want.

But this:
double = double1 + abs(double2);
will ALWAYS work with a "positive double2".

You could also do this:
double = double1 + ((double2 > 0)?double2:-double2)
or

if (double2 > 0) double = double1 + double2;<br />
else double = double1 + -double2;

if (double2 > 0) double = double1 + double2;<br />
else double = double1 - double2;

Or i don't understand what you want to do.

Why do you want to download it independantly ? It should be part of the platform SDK. Did you download the PlatformSDK ? Which version of Visual studio are you using ?

Which version of Windows are you targeting? This API is present only in Windows 2000 or above. You must ensure to define _WIN32_WINNT and WINVER to something that's above 0x500 (Windows 2000 or above) to have this API available to be used from your code.

Are you using a really OLD SDK?

Download the platform SDK from the microsoft site and integrate it to visual studio.

if you are using VS 6, you have to download platform SDK 2003[^]

If you are using any latest version of visual studio, better download the latest SDK[^]
