Visual C++ :: Member Function - Add Vertical Colour Text In Popup Menu
Jun 4, 2013I was reading a c++ code written in embarcadero ide to add vertical colour text in popup menu.
While reading the code, I had seen following instructions.
private:
Code:
void __fastcall ExpandMenuItemWidth(TObject *Sender, TCanvas *ACanvas,int &Width, int &Height);
Code:
void __fastcall DrawNewItem(TObject *Sender, TCanvas *ACanvas, const TRect &ARect, bool Selected);
The above two methods used in the code like below:
Code:
PopupMenu1->Items->Items[i]->OnMeasureItem = ExpandMenuItemWidth;
PopupMenu1->Items->Items[i]->OnDrawItem = DrawNewItem;
What is happening when we are using member function without parameters like above?
I found above code at: [URL] ....
C/C++ :: How To Change Position Of Image And Button On Window
Jan 12, 2015The question says:
Place an Image on top of a Button. Move both when the Button is pushed.
Please have a look at this code:
#include <GUI.h>
using namespace Graph_lib;
//------------------------------------------------
class rotation : public Window {
public:
rotation(Point xy, int w, int h, const string& title):
Window(xy,w,h,title),
[Code] ....
The problem is that, it is not possible to define an Image in public/private part of the class rotation. Image needs all arguments to be supplied even when declaring one. (Image is here in Graph.h)
And if I define that Image in the body of main() function, so how to provide access for void rotate() to change its position with the position of button simultaneously.
C Sharp :: Change Background In All Forms With Button Click
Jul 14, 2013I made 2 forms and Form2 has buttons with images like planets and game wallpapers etc. When I write the code for button:
this.BackgroundImage = new Bitmap(Properties.Resources._8_8008_by_amplifier404);
this.BackgroundImageLayout = ImageLayout.Stretch;
// where _8_8008_by_amplifier404 is name of the image located in resources
It only changes background in form which has those buttons as long the form is used. Once I go back to form1 it's changed to null. How to set background in all forms with a button click which will be there until another button with an image is clicked.

Aug 2, 2013I have created an application that has bunch of buttons on top and i want to change the image when I click on the button. But unfortunately I can't get it to work.
Here is the code:
if (serialPort1.IsOpen) {
tsbCommPortOpenClose.ToolTipText = "Open serial port";
closeCommPortToolStripMenuItem.Text = "Open serial port";
tsbCommPortOpenClose.Image = Image.FromFile("Red.bmp");
serialPort1.Close();
[Code] ....
The second one which changes the image to "image2" works fine. Here is the definition of image2:
namespace Regress;
...
private Bitmap image2;
System.Reflection.Assembly myAssembly = System.Reflection.Assembly.GetExecutingAssembly();
StreammyStream = myAssembly.GetManifestResourceStream("Regress.Sharing.gif");
image2 = new Bitmap(myStream);
When I do the same with the other image that I want to use, it won't work! I opened the project properties and added the image into the resources too, and it still doesn't work. It fails and says the file was not there. I've put a copy of the file in the root directory and one in "Resources" folder but it still doesn't work.

Visual C++ :: MFC- Receiving Button Click Message Failed
Oct 2, 2014I've created a new dialog in my MFC dialog based application. the new dialog contains 5 control buttons. The following happens and I don't understand why?
1. click on buttonX. (result ok, OnBnClicked message is sent)
2. click on on any place of the application, but not on the dialog.(removing focus from dialog)
3. click again on buttonX (FAILED, OnBnClicked message is NOT sent). but if instead I click on any other button in the dialog (result ok, OnBnClicked message is sent).
And when I do:
1. ...
2. ...
3. click on the dialog area just to set focus on the dialog again
4. click again on buttonX. (result ok, OnBnClicked message is sent)
**I need to do step 3 only if I want to click again on the buttonX! why?? I think it related to SetFocus() but I m not sure how.
I've tried different style like, tool windows, overlapped, popup. it happens in all the cases.
Code:
class CToolsDlg : public CBDialog {
DECLARE_DYNAMIC(CToolsDlg)
public:
CToolsDlg(CWnd* pParent = NULL); // standard constructor
virtual ~CToolsDlg();
CToolTipCtrl m_ToolsTips;

View 1 Replies View RelatedVisual C++ :: Blocking Keyboard Play / Pause Button In Windows 8?
Mar 27, 2014I am writing an application that needs to temporarily disable the Play/Pause button that appears on multimedia keyboards.
Normally, a key can be blocked quite easily by installing a low level keyboard hook (WH_KEYBOARD_LL) where the KeyboardProc intercepts the key (in this case VK_MEDIA_PLAY_PAUSE) and returns a "1" instead of calling CallNextHookEx. I have tried this with other keys (including the Windows key VK_LWIN) and this works perfectly. I also have no problems with this method under Windows 7 where all keys, including VK_MEDIA_PLAY_PAUSE get blocked.
Windows 8 is a different story. When my application has input focus, everything works as expected, meaning the VK_MEDIA_PLAY_PAUSE key gets blocked and no other application responds to it. However, when my application loses focus, my hook procedure gets called (this was verified by sending out a OutputDebugString) but other applications respond to key even though I return a "1". As soon as my app gets focus again, everything is block as it should.
After some investigation, I found that the multimedia keys not only generate keystrokes but also generate WM_APPCOMMAND messages so I added ShellProc (WH_SHELL) hook with the following hook procedure:
LRESULT __declspec(dllexport)__stdcall CALLBACK ShellProc(int nCode,WPARAM wParam,LPARAM lParam) {
// Do we have to handle this message?
if (nCode == HSHELL_APPCOMMAND) {
OutputDebugStringX(">>>>> HSHELL_APPCOMMAND");
[code]....
This procedure is only getting called when my app has input focus. Whenever I have input focus and return "1" the Play/Pause command gets blocked. As soon as I lose focus the procedure does not get called/hooked.
As I have mentioned, the code works for other keys, just not the multimedia keys.
Alternatively, another way of blocking the multimedia keyboards Play/Pause button?

Visual C++ :: How To Change Background Color Of Messagebox
Jan 5, 2015Here 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?
Visual C++ :: CMFC ToolBar - Can't Change Title?
May 1, 2014Visual Studio 2013. C++.
Created a blank, SDI MFC app.
I added a new CMFCToolBar (by hand, didn't use a wizard)
It docks OK. The commands work OK. It renders OK. No problems there.
In the code, attempting to set the window text of this toolbar has no effect. The title bar text is always "Standard". I triple triple triple checked to make sure I don't have any resource ID conflicts. In a small app as this, it was pretty easy to verify this.
The toolbar also does not show in the menu illustrated in the screenshot. (The bottom, undocked toolbar should be titled "My Page Bar" and I think it should show up in the popup menu.)
I know I'm probably missing a simple step somewhere, but I haven't seen it. It looks like its getting mixed up with the Standard Toolbar resource ID somewhere but I could see nothing in the .rc or resource.h files.
