Hello comunity,
i look for a funktion for CString's, funktion who is not casesensitive!
My problem is that i do mutch with Files, and a search in them, but when i use
the funktion from CString::Find(); , i have an problem that they 'r casesensitive,
for example, when i look for string like "code", is not the same like "CODE"!
Is here any god function for search in strings
example:

<br />
CString csString = L"THE CODE PROJECT";<br />
int iPos;<br />
<br />
iPos = csString.Find(L"code"); // here is problem, <br />
// iPos is -1 in this case, only:<br />
iPos = csString.Find(L"CODE"); // this way returns a index of the substring<br />
<br />
// and i want to look for a string no matter for case, if "CODE" or "code" <br />
// function should return a given index from a string!! :confused:<br />

"code" is in string, but i recive -1 as return value!!!

thax for any help

And what about converting the CString to upper or lower case first (with CString::MakeUpper and CString::MakeLower). If you don't want to modify the case of your string, you can first store it in a temporary string that you modify and work with it.

Hello Moonen,
in some case is this a good idea, but i can't change all file content, because this change the file, and i want to extract some parts of this file and store it
in a new varable for later to compare and some other functions!
Confused | :confused:

but tanx for reply

What Cedric meant is that you can use a temporary string which you can manipulate as you wish to get the index returned by the Find function, and then use this index on the real variable, namely this one:

You could derive a custom string class from CString and overload the Find function:

class CMyCString : public CString
{
int Find(LPSTR lpszSub, int startAt=0);
}

int CMyCString::Find LPSTR lpszSub, int startAt)
{
CString s1 = *this; //make a copy of the current string
CString s2 = lpszSub;
//Make both strings uppercase
s1.MakeUpper();
s2.MakeUpper();

return s1.Find(s2,startAt);
}

You would then be able to use your custom class in place of CString.

WM_NCHITTEST and borders

Heya everybody. I got a question about WM_NCHITTEST...

I got a window with thick border and to prevent the user to resize it, I have to interpret WM_NCHITTEST and return HTBORDER when the mouse is over the border. However... the question is... is there an easy way to know when the mouse is over the border??? Or do I have to make some arithmetical checks for this? As far as I see the problem right now, the only way to determine when the mouse is over a border is to calculate by using the lParam of WM_NCHITTEST which tells me screen-relative X/Y position.

I did a test for you, add the 3 lines:

//===============================
CMenu*pMu=GetSystemMenu(0);
pMu->RemoveMenu(SC_SIZE,MF_BYCOMMAND);
ModifyStyle(WS_MAXIMIZEBOX,0);
//===============================

the window will not be sized.

A nice tool for optimizing your Microsoft html-help contents.

Thank you. I don't know if this would work on WIN32 though, since I am not using MFC.

Use the return value of the base class OnNcHitTest.

MFC

UINT CMyWnd::OnNcHitTest(CPoint point)
{
   UINT border = CWnd::OnNcHitTest(point);
   switch (border)
   {
   case HT_BOTTOM:
      border = HTBORDER;
      break;
   ...
   }
 
   return border;
}

Win32

LRESULT CALLBACK WndProc (...)
{
   switch (nMsg)
   {
   case WM_NCHITEST:
      {
          UINT border = ::DefWindowProc(hWnd, nMsg, wp, lp);
          switch (border)
...

Well, you get the idea

You may be right

GDI+ problem

Hello Everybody!
I'v got a following problem.

I have an bmp image.
With a help of GDI+ function I conver it to tiff file (pure C++ code).

Everything worked, but the problem that generated tiff file has 96 dpi
resilution, when I want 300 dpi.

Is enybody know the way how to specify resolution in GDI+
when converting images?

Re: GDI+ problem

PJ Arends23-Mar-06 6:50

I am assuming that you are using Image::Save() method to save your tiff file. Have a look at the encoderParams parameter. I would start by reading http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdicpp/GDIPlus/usingGDIPlus/usingimageencodersanddecoders.asp[^].

I've looked at MS documentataion and have found only folowing 3 parameters:
//=========================================
TIFF encoder parameter Allowable values:
- Compression EncoderValueCompressionLZW
- EncoderValueCompressionCCITT3
- EncoderValueCompressionCCITT4
- EncoderValueCompressionRle
- EncoderValueCompressionNone

ColorDepth : 1, 4, 8, 24, 32
SaveFlag : EncoderValueMultiFrame
//=================================

Nothing about dpi Frown | :(

I've solved the problem!

The Idea is using Gdiplus:: Bitmap
instead of Gdiplus::Image
In this case there is a function Bitmap->SetResolution(REAL x, REAL y)
that allow to do it. Smile | :)

How can I pass an array as a function parameter?

Cristoff23-Mar-06 2:51

Cristoff

23-Mar-06 2:51

here is what I want to do:

I want to swap the some elements of an array so I want to make a function like that:

int arr[] // this array is initialized

...

swap( int a[])
{
//swap parameters
}

swap(arr); // use the function

printarr(arr); // print the resault

The question is: how should I pass the array to the function properly, so that it changes the values of arr outside of its body too?

Pass the array as a pointer.

void SwapArrayVals(int iVals[],int size){
    // your code here
}

and to call the function

int iData[2] = {11,22};
SwapArrayVals(iData,2);

int iData[2] = {11,22};
SwapArrayVals(&iData[0],2);

Also, it's not always necassary to pass the array size, but it is good practice and avoids writing outside your array.

Also, it could be interesting to have a look at the containers (particularly the vector) of the standard template library (STL). Basically, it will help you to maintain arrays that can be resized easily, ...

Hello all,
Am newly working with bitmap, i do have many questions regarding this.
At present am working on Visual C++, but am devolping code in C without any dialog based(No GUI), just with CLASS view and FILE view, am almost finished with the work, but the problem, now i have to open a bitmap to plot the output data on the bitmap.
Is it possible to create a Bitmap in C or should i use VC++ dialog based application only? Is there any special function?

Its possible to open a bitmap the same as any other "text" file. You can also use the CreateBitmap() LoadBitmap() ... functions, but I think these require that you include windows.h or at least GDI.h into your project.

I'm not sure exactly what you are rying to do, but if you do some research about DI (Device Independant) Bitmaps, these allow you to manipulate each pixel in the structure.

hello,
#include "windows.h"
#include "windgi.h"
#include "GDI.h"
CreateBitmap(100,100,256,16,const void*lpvbit);

am getting an error as "cannot open GDI.h"
what could be the reason?
