ON_WM_CTLCOLOR(...) works for all the other controls but not the tab control.
Code:
void CEasyWebStoreUploaderDlg::DoDataExchange(CDataExchange* pDX)
{
CDialogEx::DoDataExchange(pDX);
DDX_Control(pDX, IDC_TAB_CTRL, m_tabCtrl);
DDX_Text(pDX, IDC_EDIT_STATUS, m_strServerStatus);
DDX_Text(pDX, IDC_EDIT_UPLOAD_RESULTS, m_strUploadResults);
}
Here is what I did,
Code:
oldHook = ::SetWindowsHookEx(WH_CALLWNDPROCRET, CallWndRetProc, NULL, ::GetCurrentThreadId());
MessageBox(...);
UnhookWindowsHookEx(oldHook);
Then within the callback function CallWndRetProc, I tried to change the background color of the dialog,
Code:
PAINTSTRUCT ps;
HDC hdc = BeginPaint(msg->hwnd, &ps);
::SetBkColor(hdc, RGB(255, 0, 0));
EndPaint(msg->hwnd, &ps);
But it doesn't change the background color of the dialog. I wonder what is the right way to do that?
I am saving my data in Excel File Format.
I am using CDataBase class and its methods like OpenEx ,ExecuteSQL etc. The program is working fine.
Now I need to change back-ground color of some data base records.
How to do this in MFC ?
I have a derived CComboBox class, where I tried to change text and background of edit from CComboBox, just like this:
Code:
HBRUSH CMyComboBox::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) {
HBRUSH hbr = CComboBox::OnCtlColor(pDC, pWnd, nCtlColor);
// TODO: Change any attributes of the DC here
//if(CTLCOLOR_EDIT == nCtlColor || CTLCOLOR_MSGBOX == nCtlColor) {
[Code] ......
but is not working if CComboBox has CBS_DROPDOWNLIST style ... is working only for CBS_DROPDOWN style ... why ?
I used onctlcolor() method to set the background color for the controls & Dialog. I run my application, working good but after 15 mins the below error occured,
Application Error:
The Required Resource Was --------> Shown message box

I am writing a GUI application with C++ Visual component Libraries and Win32API under windows OS.
As part of this app, I have to change color of the MS Windows button control depending on the external state.
I understood, Win32 will not support changing button control color directly as it will not support for this.
how to change the button color?
Okay, I have a form and I have a tab control thing. On the second tab, I have a button which is supposed to turn the background green.
So, I have this:
#pragma endregion
private: System::Void greenButton_Click(System::Object^ sender, System::EventArgs^ e) {
this ->BackColor = System::Drawing::Color::Green;
But clearly that just turns the FORMS background green. How can I change the TAB background to green.
I am working on this project where I need to update an edit box every couple of seconds with a status and based on the status I need to change the color of the background to a particular color.I am able to update the edit box with the status but is clueless on how to update background color.I have read some info on line about this but is confused.This edit box is on a tab in a dialog. Also, on this tab is a Groupable List Ctrl.

This is for excel . I have a form with 2 combobox and 1 textbox ...
combo 1 : user can select a column ; let say column A
combo 2 : user can select an operator ; let say = (equal)
textbox : user can enter value ; let say 2
so my code is like
if (column A == tb.text) {
execute code here
}
but the problem i have is during run time i allow user to add more controls to the form
if ((column A == tb.text) && (column B == tb2.text)) && //may be more if user add {
execute code here
}
how do i handle this 'cause, how many will the user add to it, and the code should change when user add new control to it.

i had created a client server program in MFC using TCP but by doing this the server can only work on one computer because you have to tell the client the ip address to connect to i.e
Code:
ServerAddr.sin_addr.s_addr = inet_addr("10.13.31.112");
so i want to change my code so that i can use broadcasting but i found out that it only works using UDP. I tried changing the code but the error message "error with sendto: 10047" displays when i run the program.
that error means
Address family not supported by protocol family. An address incompatible with the requested protocol was used. All sockets are created with an associated address family (that is, AF_INET for Internet Protocols) and a generic protocol type (that is, SOCK_STREAM). This error is returned if an incorrect protocol is explicitly requested in the socket call, or if an address of the wrong family is used for a socket, for example, in sendto.
here is the code from server:
Code:
WSADATA wsaData;
WSAStartup(MAKEWORD(2,2), &wsaData);
int port = 7171;
if (param)
port = reinterpret_cast<short>(param);

View 1 Replies View RelatedI m trying to place an image on the colour frame of the Kinect live video. I m able to overlay the image using alpha blending mechanism.
The image used is a bitmap image of dimension 128*128.
The Kinect has a resolution of 640*480.
IDE used is Visual studio 2010 and I m developing using c++.
The Kinect has a render target whose size is taken as 640*480 so that it stretches for the complete window. So when I try to overlay the image it appears 5 times because of this stretching.
If I increase the image size to 640*128 i get a single image that is stretched horizontally across the window with dimension 640*480.
I have created a function that will create a render target with bitmap properties and size equal to 640*480. This is used to store the data from the Kinect, frame by frame, and draw it on to the screen
So I think when I overlay the image, it gets replicated 5 times to meet the render target size.By default the image is placed at the left top position.
My doubts are
- How can I use different functions to specify the size of render target for Kinect as 640*480 and the size of render target for bitmap image as 128*128.
- How to I give overlay or place the image on the live video at a specific location.
i wish to plot a mathematical function on a 2-dimensional grid. The function will be represented by 3 sets of floats, x-values, y-values, and z-values. Obviously, it is impossible to plot 3 such data sets on a 2D grid, so one approach is to use pixel coloration to represent the z-values.
Those examples (and there are many to be found) show something like the function of the complex variable z, f(z) = exp(z). I have attached a exp(z).jpg example of the imaginary part of the plot exp(z).
My question is: How to accomplish such a gradient colorization, assuming one already has the data?
I have experimented with Gdiplus SetPixel, but I have not figured out how to produce a smooth gradient.
Here's my attempt to create a simple gradient:
Code:
CDC * pDC = GetDC();
Graphics graphics(pDC->m_hDC);
CRect r;
GetWindowRect(&r);
ScreenToClient(&r);

I needed to change Default Text attributes (font and color) . So I wrote following code , UnicodeTextOut function. I called this function once in each 55ms to update the display screen. but I observed that my Screen used to become grey like a crash after sometime . If I use Minimize an Maximize window , the screen was restoring back for some time.
When I thought over the code , I got my mistake that CreateFont initialization should be done once in the program and probably outside the function.
void UnicodeTextOut(int x, int y, CString s, UINT justify,int GreyScaleFlag) {
HFONT hFontUnicode;
HFONT hfOld ;
hFontUnicode = CreateFont(16, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0, _T("Aerial"));
[Code] ....
Then I shifted the line hFontUnicode = CreateFont(16, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0, _T("Aerial")); in my screen class constructor and made hFontUnicode global .
This solved my problem as expected. Why a system crash after certain no of CreateFont calls ?
