I've already used the GetProcAddress function for half a dozen functions but it seems I've got a problem with that one. Might be a problem with the prototyping but there are few pages about it on the web and it is the first SH* function I try to get the address for.
I tried all the prototypes I could imagine WINAPI, STDAPI, STDAPICALLTYPE with extern "C", dllimport and other __cdecl, __stdcall gave nothing.
So here's the code, any idea welcome:
typedef int (__stdcall *LPFNSHGETICONOVERLAYINDEX)(LPCSTR, int);<br />
HMODULE hMod = ::GetModuleHandle(_T("Shell32.dll"));<br />
if (hMod) {<br />
LPFNSHGETICONOVERLAYINDEX lpfnSHGetIconOverlayIndex;<br />
lpfnSHGetIconOverlayIndex = (LPFNSHGETICONOVERLAYINDEX)GetProcAddress(hMod,_T("SHGetIconOverlayIndex"));<br />
if (lpfnSHGetIconOverlayIndex) {<br />
m_nIndexOverlay = lpfnSHGetIconOverlayIndex("C:\\", IDO_SHGIOI_LINK);<br />
}<br />
}<br />

Try SHGetIconOverlayIndexA or SHGetIconOverlayIndexW

I have found several nice articles on customizing and superclassing CFileDialog to do things like change the dialog size and defaulting to a particular view (list, detail, thumbnail) when displaying files. I haven't found anything on how to change the file display order. I would like to show the files in detail view (done) and then order them by date, descending, in the view. There doesn't appear to be any programatic way to do this, short of creating my own file dialog box from scratch. I have attempted to send messages faking a left click on the date header, but that does nothing.
It would be really nice to show the user the newest files to process. Any ideas?
Thx in advance

**Sigh**
Nevermind. I figured it out. I had to fake up a WM_NOTIFY to the undocumented control that houses the listbox that contains the file names. I had to fake a left click and populate an NM_LISTVIEW structure and pass it into the SHELLDEF_view window message processor. The fake was to tell it the message was from its list control. Send 2 messages to order in descending order.
Whatta zoo.

How to get the same intensity after stretching an image
eg:
Let intensity of a square of 1 unit = 1 x I1
If I stretch the square to 2 units then the intensity = 2 x I2
Both these intensities should be equal
1xI1 = 2xI2 = k(constant)
I am using bilinear interpolation for stretching but the intensities arent equal.
Is there some other method for stretching so that I ll get same intensity in both the images.
Pls Help

Well I guess you can solve the problem just by dividing Intensity in each pixel by a stretch factor. In above example- just divide it by 2.
But I think your problem could be deeper- if you imagine an image,
and you zoom in (for example you double the number of pixels in both directions -> you see 4 times more pixels), it means that you are watching sub-pixels, and they have area of 1/4 of original pixel. Therefore you have 4 times more pixels, but each of them has just 1/4 of unit area.

Thanks a lot
Is there any algorithm or filter which I could use to reduce the intensity? It should work both ways (stretching and shrinking).

I have created one dialog box. Then I have created a view class
with help of menu Insert -> Form.
CMultiDocTemplate* pNewDocTemplate = new CMultiDocTemplate(
IDR_TRIAL_TMPL,
RUNTIME_CLASS(CMDIDocumentDoc), // document class
RUNTIME_CLASS(CMDIChildWnd), // frame class
RUNTIME_CLASS(trial)); // view class
AddDocTemplate(pNewDocTemplate);
Even New template is seen in File -> New but it does not display
my dialog but gives error "Debug Assertion Failed in viewform.cpp'
I am sure I am missing some step while creation of view class
Please help me

Have you looked at the line in viewform.cpp to see what condition is causing the assertion to fire?
|

No but If I replace my view class name with any view class made by the earlier programmers view class the application is opening its dialogs. I have gone in viewform.cpp but it seems to be useless it is mfc's cpp.

If you find the reason why viewform.cpp gets into trouble, then you might find out the cause of why it happens.

IT IS TELLING LINE NUMBER IN VIEWFORM.CPP WHILE DEBUGGING ,IT IS NOT GOING TO THAT ERROR. WHEN I AM OPENING VIEWFORM.CPP THERE ARE MANY FUNCTIONS HOW CAN I UNDERSTAND WHERE IS ERROR?
I AM BEGINNER SO I AM SURE SOME SILLY STEP I AM MISSING
WHILE CREATING VIEW CLASS PLEASE HELP?

I'm using VS 6.0.
When your program has aborted (while debugging it), take a look in the window below the code window (in Visual studio).
There you have a small window with the name "Context". The text line itself shows the function where the program took a dive.
Now, if you press the down arrow at the right of that text line, you will get a list of all of the functions your program has on it's call stack.
There will be (at least) one function name that you will recognize (because it's in your program).
Select that line and the editor window will show your code, together with a green arrow. The green arrow will point at the line (still in cour code) that was the reason for the error.
Another way to do this (sill in VS 6.0), is to select (from the VS menu), View->Debug Windows->Call Stack (or press Alt-7).
Double-click on the most upper line that has a function name that's in your code and the editor takes you to the line in error.
And please, for your own sake, get a book about Visual Studio. I'm sure you will find the time spent on reading to be worth while.
Good luck.

Hello, everyong!
who can tell me the difference between "std::wstring" and "std::string" ? For unicode, I want to replace "std::string"
with "std::wstring", what I should pay attention to ? Please instruct me, thanks a lot!

Hi
I am doing a image prcessing project in VC++, I am using bilinear interpolation for stretching the images but the image intensity varies before stretching and after stretching.
for eg:
If the image intensity for a square of 1 unit = 1xI1.
If I stretch the image to 2 units then the intensity should be 2xI2
both the intensities should be equal
ie 1xI1 = 2xI2 = k(constant)
Pls help

I think this is a result of roundoff. Are you doing your calculation with floating point numbers and translating them back to integers?

Thanks for ur reply
Yes I am calculating it with floating point numbers and translating it back to integers.
Is there a problem with that? or should I use density filter to get the same intensity

i want to include the feature for logarithmic plots in my application ...but i am having trouble scaling the y-axis ...(bcoz points they are not equally spaced.)
anyone has an idea or expereince in this regard
thanks
|

What do you want to do exactly ? Plot a point on a logarithmic axis ? That is convert his value into a screen position ? If yes, you can use the following code:
long Offset = (int)floor((log10(Value)-log10(m_MinValue)) * GetAxisLenght()/(log10(m_MaxValue)-log10(m_MinValue)) );<br />
<br />
long ScreenPos = m_StartPos + Offset;
Value is the value you want to plot on the axis
m_MinValue is the minimum value of the axis (the real value I mean, not a screen position)
m_MaxValue is the maximum value of the axis
GetAxisLenght() returns the length in pixel of the axis
m_StartPos is the start position (in Screen coordinate) of the axis.
It works fine because I use this code in a chart control I developped some time ago.

Dear Readers,
In my project i m facing problem of memory model at some stage if my internal memory usage is exceed then its gice me error or some times it dont allow to open perticuler window. this is done if i make my double array size id huge like 800000 count.so please help me wht to do for this.and i cant able to use CArray of such type of things. so pleas ehelp me for this.

In 16-bit programs, there was the option of different memory models, but in 32-bit, and 64-bit, it is Flat. So you can allocate as much memory as the OS will allow you. The problem seems like the OS is denying you memory. Solution should be (I think) Allow more hard disk space on the drive where windows is installed. And, Install more Ram.
this is this.
