Is it possible to edit the message map at startup instead of just having it set at compile time?
I'm reading some values from an XML file at startup. The menu options will be determined from what I find in there. But I need to assign those menu options to the message map.
I'm trying to take a value from an edit box and display it in the edit box as hex. I'm using this code:
CString buffer;
int intbuf;
m_edit[5]->GetWindowTextA(buffer);
intbuf = atoi(buffer);
buffer.Format("%02X", intbuf);
m_edit[5]->SetWindowTextA(buffer);
If I include the last line of code here I get a stack overflow error. If I don't include it, I can run through the debugger and the buffer CString is converted to hex just like I want, I just can't display it because I get that error.
I'm trying to create an edit box in a CView.So far, this is how far I've gotten:
With this code
Code:
// .h
CEdit m_MyEditField;
// .c
m_MyEditField.Create(WS_CHILD | WS_VISIBLE,CRect(40,40,500,Y+55),this,0x1552);
m_MyEditField.SetWindowText("this is my CEdit field");
As you can see, the edit box doesn't look like the ones in a dialog, which is what I'm trying to accomplish.
Is there possibly some other class I should be using for the edit box?Or another setting for .Create?
I have a tabbed dialog with a couple of Separate dialogs. I created classes of CDialog for each dialog. Im trying to get the text from the edit control from the tabbed dialog and it appears in a message box when I press a button on the main dialog.
Code:
myDialog test;
test.UpdateData(TRUE);
CString bla = test.m_edit1;
test.UpdateData(FALSE);
MessageBox(bla,bla,MB_OK);
The m_edit is a variable of CString for the edit box
it gives me a error and crashes.
How do I get the text from the other dialogs edit control?
Found an online suggestion of using an rc2 file and cut and paste stuff from .rc file to .rc2 file to see which line causes the problem but don't know how to create a blank .rc2 file. Problem started after I ported from VC++ 6 to VS2010.

Any button action (up or down) doesn;t register when the mouse is clicked on any of the edit controls. There has got to be a simple way to do this.

I have a simple dialog based app that performs some time consuming file manipulations. The activating method contains the customary
Code:
CWaitCursor wait;
The hour glass initially appears, than after a few seconds, the dialog title bar indicates 'not responding'.
This is misleading to users as it suggests the application has ceased to function when, in fact, it's working just fine. I would like very much to eliminate this 'not responding' message but havn't a clue how to do it. Have any of you dealt with this problem, if so, how?
is it possible to take integer or char data type on message box to V C++?

But I can't, it went so fast so long as I switch from VS to the application program, the breakpoint is hitted again, then the application is frozen again. I don't know how to setup a conditional breakpoint.
View 3 Replies View RelatedI'm looking for a resource (possibly CPP) for which I could do the following on a windows and linux machine:
1) type a string message into a GUI control (or some other input that can be accessed by the resource).
2) run a resource script that puts the message through a hash function (or a custom hash function) and outputs the hash string.
3) have a reverse function available in order to decrypt the message in an input fashion just like step #1.
what open-source resource might be the best for this? Right now I am imagining typing a message into a text file, saving the file to a hard drive location, running a script on it replacing the old file with a new file that just has a hash string in it, then using that hash string for the encoded message.

I want this .dll to make a ping or to send a message like hello somewhere, and IF ping or message doesn't receive an answer that's means the user has suspended-terminated this dll from the exe then the exe will close. How can i do that?
I have a DLL developed using pure VC++ (all unmanaged code that doesn't use .NET framework). This DLL will be deployed in different client PCs within a network and will act like an agent.
Now I have establish a communication between this DLL and a WCF web service, that will be deployed in a server PC. The Service will first get a list of PCs either name or IP Address within a network using LDAP (Active Directory) and once, we get the PCs, I have to establish a communication between the web service and the agents that reside in these client PCs,

I'm trying to write a program that passes Windows messages back and forth from another program that controls a laboratory instrument. I was able to write a program that successfully passes instructions, as evidenced by the instrument doing what I tell it. However, I am having trouble getting a return status from the instrument. The manual instructs the following:
// demo code, etc.
// send message to the instrument operating software here...
SendMessage(hwnd, WM_COPYDATA, tag, (LPARAM) &cd)
Either a completion message or return data is returned. Remote commands ReturnStatus, ReturnTiming, and ReturnData return data. In either case, data is received through an asynchronous windows message inside Win32 COPYDATASTRUCT type data packet.For example, a typical OnCopyData window callback is shown below, where the string data retrieved is finally stored into a Microsoft CString object. Note the use of variable replyTag, discussed above, which is used to isolate the correct windows message returned.
BOOL CUserDlg::OnCopyData(CWnd* pWnd, COPYDATASTRUCT* cd) {
….
if (cd->dwData == replyTag) {
/* String pointing to status */
CString retStatus = (char*) cd->lpData;
}
….
}
I can't tell if my problem is in generating the replyTag, getting the HWND to my own console window, or the actual receiving part of the code.
When setting the replyTag, the manual instructs: UINT replyTag = RegisterWindowMessage(“SOFTMaxProReplyMsg”);. However, I have to put an "L" in front of the string or I get a data type error (can't convert const char* to LPCWSTR).
When setting a HWND for myself, the manual instructs: HWND MyWnd = GetSafeHwnd().
That produces an error because GetSafeHwnd is a function of the Cwnd class, and I don't have a Cwnd. I have replaced it with HWND MyWnd = GetConsoleWindow();
When listening for the reply message, the manual instructs what I quoted above. However, I again don't have a Cwnd. I therefore simply used
if (cd.dwData == replyTag) {
CString retStatus = (char*) cd.lpData;
}
The above if statement always evaluates false, and the cd.lpdata contains the message that I had sent out instead of a reply message. How to get a reply using my console application. Here is the full code of my function:
Code:
#include "stdafx.h"
#include<iostream>

I'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;

I have finally got around to developing C++ & MFC using Visual Studio 2012, to build a full GUI Windows application (not sure if I have made the right choice). Though admittedly in two months time I do have a dialog window at my beck and call.
Now I have discovered a flaw (suspect) partially caused by the design of this program not all following the same principles, nor written by the same people and long predates me. Let describe the situation.
I have a dialog I have created as a class which has a combo box. The list of items are populate during the OnInitDialog() function just fine, except if the file where the detail is not yet read from that combo box would not have any items other than the default. This is to be expected in the use of the program, so fine.
However, if the dialog (modeless) was already open and active, when the user went up to and selected the menu command (main window) to read that file that CPtrList data structure that held that data would not populate that Combo box on my dialog.
So what I would like when I am done reading the files contents is to detect if my dialog is opened and if so send it a message to Activate (force a call to OnActivate()). I have gone to the event list for the dialog and exposed this event handler from the resource editor just fine.
I see the syntax of OnActivate() is
void MyClass::OnActivate(UINT nState, CWnd* pWndOther, BOOL bMinimalized);
So nState is an Unsigned Int of the current state of the thread/window (not sure)?
CWnd* pWndOther is the CWnd of my other Window that wants my dialog to activate I think which is the main application since it was on the a menu that this function was called to read the file.
bMinimalized is whether my dialog is mimalized(?)

I am trying to build a program which would start at the start of the computer, so for that when ever the user would run the program the program must get copied in the startup folder of the Windows I guess or anything else so that the program runs as soon as the computer is booted.
I this program would create a .vbs file n the startup, in that vbs file i would write the code for speech. so what the computer would greet you when you switch on the PC.
Here's what I tried:
#include<stdio.h>
#include<conio.h>
#include<string.h>
[Code]....
So my motive behind this code is that, this should create a .vbs file in the startup folder in that vbs file the above code would be written,
(Dim speaks,speech
speaks=Hello!
set speech=CreateObject(sapi.voice)
speech.Speak speaks) a
And then the vbs file would execute as soon as the computer starts, and then it would speak "Hello!".
But the problem is that i am not able to create a file in the folder when i run the program the file is not created, i do not get any error but nothing happens as well.
I have to do a program that checks the startup type of several winservices, but i cant seem to find an answer (that works).
I have tried using ServiceController, but it doesnt contain that info. I have tried using ServiceHelper but i cant find the package that contains it, i tried invoking some dlls but that didnt worked either, and some more that i didnt even understood..
