Visual C++ :: CDialogBar Moves Content (other Windows) In MDI Application When Docked At Left Side
Feb 19, 2013
I have a question concerning the CDialogBar (:CControlBar).
I have a MDI application with a dockable toolbox (CDialogBar).
The user is able/allowed to move the DialogBar and to dock it at the right or left side When I dock at the left side, the content of my mdi-application (so all other open windows) are moved right (so the dockable bar moves the windows).
If i dock at the right side, nothing changes.
How can I change the behaviour of the bar, that the windows inside the application keep the same position when I dock left ?
(Problem is, that my windows are aligned on the right side of the application). When I dock the bar on the left, the windows are getting moved in the not visible area.)
How do you add a value to the beginning of a string instead of the end?
This is for an assignment and I have to convert the user input (always assuming its a valid decimal number) to binary and store it in a string. I've got up to dividing by two to get the remainder ...
I am new in Visual C++ and I have to make an MFC application with "child" windows. Here is what i need to achieve - [URL] ..... As you can observe when you click on the cross of popup window or child window 2 both are closing.
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
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> #include<vector> #include<string> #include<afxwin.h> using namespace std; void SendCommand(string command) { // Get tags to identify the receiving and sending messages
I want to write my own application which would fetch some data from a web site. I need to parse the HTML code of the web site and get the data.
About the application:A form (main form) that will contain data arranged in rows. Some of the data comes from a web site and some of it comes from a database.The data that comes from the web site needs to be updated every few seconds so I need to keep fetching the data from the web site.The main form will contain a button "add" which when clicked will add a new row. New data can be added to this row by the user.
I am not sure what to use for this. I have been writing the application as a Windows Form Application (Visual C#) but I do not know whether this is the best choice. Should it be a windows form application or web application? Should I use something else?
I dumped all symbols into C:WindowsSymbols folder, It takes more than 2 minutes to load an application which really surprises me. Why and when should I use those symbols?
My program (Test) is a basic MFC AppWizard (exe) created project. I have followed the steps in the link below to create a docked dialog box (myDialog) using VC++. [URL]...
The dialog box works, however, I have 2 issues that I am trying to resolve.
1) I have added a button to the Dialog box, however, when I run the application they start as disabled (note: the Disabled option on the Button Properties is unchecked). If I add function myDialog::OnButton to the myDialog class, the button remains disabled, however, if I add the function CTestView::OnButton to the View class, the button becomes active and works. How can I make the button work from the myDialog class?
2) I would like to be able to change an Edit box in the same dialog box when I click the button. How can I access the pointer to the myDialog from the View class?
I have an problem with a CDialogbar if my app runs on a system with two screens (side by side). I can not resize it while the CDialogbar is in floating state on the second screen.
I figured out that the problem is the mfc-function CDockContext::Stretch().
It limits the CDialogbar to the primary screen (using ::GetDesktopWindow() to verify the position).
I have a Windows desktop application with 2 projects. The main project, and a simple windows service project. I have written the service and the service installer. I have added code to my main window to start the service, but I can't figure out how to install the service when the application runs for the first time, or is installed. Ideally I would like the service to be installed when the application is installed, I'm just not sure how to do that.
I'm building a Windows Form Application using MVP Design Pattern; the application is quite simple, it just calculates the sum of two number; So I have a form in which are located tree textbox: number1 number2 and result, plus a button to perform the action.
I have been struggling to read a certificate in windows store from C++ DLL, but its not happening. from console application I can but when same code built as a DLL and tried to access from a separate console application. I think its not going to windows store to read the cert.
I am creating windows application in that i wan create dynamic controls so that i want to give line break after each control in panel.I had tried
panel1.Controls.Add(new LiteralControl("<BR>"));
but it gives error like : "The type or namespace name 'LiteralControl' could not be found (are you missing a using directive or an assembly reference?)" Also have tried adding namespace for leteral control bt it not accepting.VS10 automaticaly get restart if i trying to add system.web.dll
I wrote this code behind a button " colordialog.showdialog(); File.WriteAllText("dlg.txt",this.BackColor.Name); " And I wrote this code in Form Load as well " this.BackColor = Color.FromName(File.ReadAllText("dlg.txt")); " but I got an error and I dont know what is this.... "Control does not support transparent background colors"
I have a dialog box with several edit control boxes and I want to identify the edit control when I click the left mouse button on it. 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.
The problem is that I want to scale the output. I was trying to send message to my control before blitting:
SendMessage( EM_SETZOOM, numer, denom ).
It scaled the control itself, but the blitted context was still the same size as original content CRichEditCtrl (befeoe scaling). Is there any way to blit/render scaled content of CRichEditCtrl to any device context (screen/paper) ?
I am currently making pong using visual C++ with the SDL libary. I find that the ball moves too fast for the players and needs to slow down. The code for the movement is in a while loop and vairies speeds 1 - 2 (X and Y).
