I'm currently making a math program in c++ windows form application. I'm trying to make it so where the user presses the number button I such as 1 button to display a 1 in my textbox.
Code:
private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) {
}
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;
[Code] .....
Is it possible to display a message at the bottom of a dialog box shown in the attachment? If so, how?
View 5 Replies View RelatedI'm trying to create a dialog where some of the buttons have pictures on them, rather than plain text. I notice that under the button's properties, under the "styles" tab there's a checkbox "bitmap". I can't seem to find any easy way of setting a bitmap.
View 4 Replies View RelatedI would like to have my program pause at a certain screen but not to have the "Press any key to continue..." message or the press of a button. In my program, the code looks similar to this:
for(;;)
{
cout
cin
cout
cin
...
//
here, I want to have a pause to view what the for loop has come up with but to not have a message display or a button press needed. At the end of the loop, I want it to pause before looping again. IS this possible?
If so, how can I implement it into my program?
I want to display data from text file in list view and in tree view root will be file name, but i dont know how to do it, the problem is with displaying text file data in list view, i don't know anything about that. text file data is very simple. It is just a square matrix of double values like:
21.06 34.06 5.0
12.78 45.25 6.9
12.89 45.98 5.5
in list view i want to display it.
I am trying to display some data in text format on a dialog and I am using a CString to do it. Below is how I coded it.
Code:
CString outputStr;
CString auxStr;
// Add header
outputStr.Format("");
auxStr.Format("%-7s%-20s%-7s%-20s%s
[Code] .....
But the output rows are not aligned as shown in the attached picture. There a two problems.
1. Data rows don't align with the header row.
2. When the first element of a row changes to two digits, the other elements are shifted.
According to MSDN [URL] ...., CString::Format() works the same way as printf(). I wrote a small program using printf() to do the same thing, and the output in the console are perfectly aligned.
What have I missed when doing the display in GUI?
I was wondering if it's possible to display output message without using console.write or any console function

View 1 Replies View RelatedI'm writing the program below to take an integer input for temperature and display a cheesy message for different ranges for each day of the week.
I tried using two if statements, the first to determine if the input is valid, and the else display that it was invalid and to try again.
The second set of if (if else) statements would evaluate a number input and display the cheesy message based on the value, or if it was out of range, to make you re input that days temperature.
I understand that the else statement is linked to the closest if statement, unless brackets are added to prevent this. I thought my brackets were correct, but I keep getting [Error]'else' without previous if'. The red lines are the if and else statement I'd like to be linked, and tried to do so by enclosing the 2nd if statement in brackets.
The assignment doesn't require the error checking, but if I don't use some form of it I believe it will just loop. Again I have to use the last 4 lines due to instructors rules, and have to use scanf and not strings or arrays.
This program will ask the user what the temperature will be for each day of the week. The integer input from the keyboard will be tested in a series of IF tests and a message will be printed depending on the temperature.

#include <stdio.h>
#define MAX 100
#define MIN 0
int main() {
int day = 1;
int temp;

I need to have a program display an error message if the variable entered isn't an integer but then I want it to cin again. I have this but it doesn't work:
cout << "Enter an Integer: " ;
for (;;) {
cin >> var;
if (!cin) {

I am not sure how to do what I want and this doesn't work, it just repeats That wasn't an int.. over and over again.
I am working with repeater.. Actually i have placed a linkbtn in item template.. In that linkbtn i am displaying names from database.... And i have created an event for the lnkbtn.. In that event i want to get the text property of linkbtn....

View 1 Replies View RelatedI 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 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.

View 2 Replies View RelatedYou place a breakpoint at one of locations within the message loop. But I want the breakpoint to trigger when I click on the application window, for example. 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:

#include "stdafx.h"
