How can I save an CDocument programatically, without to bring him to the top, only if I get a pointer to that document ? I mean if I have several document opened into a MDI app, and if I have a pointer to one of them, to save it without to turn them as active childs ?
View 3 RepliesI'm developing an MDI(MFC) application (with MSDEV 2010) that creates few pairs of doc-view.
From the CDocument object I want to access the CMDIChildWnd object to update the status BAR.
How can I do it ?
I am attaching a sample project. Basically what this project does is that I initialize a variable map<CString, bool*> m_mapTest in CView::OnInitialUpdate and then pass the variable to CDocument class. On the other hand, within the function OnSaveDocument defined in CDocument I check m_mapTest. To my surprise, the CString part of m_mapTest is correct but the bool* part of m_mapTest is wrong(I pass an array of bool in CView::OnInitialUpdate).

Code:
CString szFilter = "XNRep Files (*.xnrep)|*.xnrep||";
CString s = "xnrep";
CString t = "";
CFileDialog fileDlg(FALSE, s, t, NULL, szFilter);
if(fileDlg.DoModal() == IDOK)

After the file dialog opens up, I enter the name of the file and select OK button. But the file does not show up in the directory I am saving to.
I have a problem to set sliderposition programmatically. This is my try:
//pointer to my slider control:
// On the begining the range ist 1 to 10
// and the position is on 5
// change the range:
pSliderCtrl->SetRange(1, 100); // ok no problems
Now, how to "move" btw. how to redraw the position of the slider thumb programmaticaliy with c++? Need to send some message, if yes what message i need to send to slider control to move (reposition) the slider thumb?
I try with
// first:
::SendMessage(pSlider->m_hWnd, WM_NOTIFY, TRBN_THUMBPOSCHANGING, 0);
// then with:
::SendMessage(pSlider->m_hWnd, WM_NOTIFY, NM_RELEASEDCAPTURE, 0);
but nothing happens?
I have tried everything I can think of to get rid of the 'Save changes to Untitled?' message box that appears every time my SDI split app tries to load a new file. The problem is that the message appears inappropriately, both when no previous document has been loaded or should exist, and even after File / New has been envoked. I have attached a small demo program to demo the problem. Inspecting the SpVwTrDoc.cpp NewDocument and OnOpenDocument, and elsewhere, you will see that using SetModifiedFlag(FALSE); has no effect.

But my problem is that when I save the image to file the result is just a black screen.

How to fix it and to get the rotated image?

View 1 Replies View RelatedI am overriding OnSaveDocument in my MFC document class to strip out the carriage returns when saving my app's document to a UNIX file system but not when the user is saving a file to a Windows file system.
Is there a way to determine if the lpszPathName in OnSaveDocument(LPCTSTR lpszPathName) is a UNIX or Windows file system?
Note, I want to avoid hard coding server names and I want to avoid overriding the FileSave dialog and forcing the user to select Windows or UNIX.
I've been trying to figure out how to implement a way to save this board state throughout a user's inputted path. At the end, I need the output to print out the board states (user's path) of how he or she got the puzzle solved. This puzzle is the 15 Puzzle; but we have it to change by the user's input on what size they want to play (3x3 to 5x5). How to save the board state of each user input, then print those out in order from beginning to solved puzzle state. Subsequently, I would also need transferring the board state to change with using a vector to store the size based on user input. How to proceed, using a first search to solve the puzzle from the current board's state.
calculations.h
Code:
/*Calculations set as a header to keep compiling simple and faster*/
#ifndef calculations
#define calculations
int solved[5][5];
void initialize(int board[][5], int);
void slide(int board[][5],int move,int);
bool isBoardSolved(int board[][5],int);

View 5 Replies View RelatedI am trying to make a utility program for work that will update multiple projects with local dll references. Basically I work with two solutions (for talk sake solutIon1 and solutIon2). Generally solutIon1 will reference the dll's built In solutIon2 which reside on a server. However for debugging proposes I sometimes need to D/L the solutIon2 projects and build them local-ally, so that I can reference the solutIon2 dll's local-ally (this Is so that I can easily attach the dll and step Into the code). However this require changing the reference paths, so that I am pointing to the local-ally built dll's, which Is quite a laborious task.
So the question is how would I update references in solution1 from the program that I am making. I don't really know what to start reading about as I have never done anything like this before.

I'm trying to get my C program to perform a few shell commands in a Linux environment, one of them being mount. The specific command is:
Code:
mount -o rw -t ext3 /source /destination
If I put the above command in a system() call, it works. However, i tried to call mount directly, as defined in sys/mount.h, as follows:
Code:
mount("/source", "/destination", "ext3", 0, "rw");
This doesn't work - it throws me back the error "Invalid argument".
Did I translate wrongly? What's the correct syntax?
Is there any way to programatically find if the given code is taking recursive approach or iterative apporaoch using concept of files in C programming.

How do you programmatically expand a url link to its true location?
Do you know about tinyurl.com and baidu.com? Baidu.com is a search engine that tries to discourage people from using their web site to make metasearch engines by hiding their links in a way that is a lot like how tinyurl.com works. TinyUrl.com is a web site where, if you want to present someone with a link to something and that link is long, you can use tinyurl to produce a tiny url for presentation purposes.
Anyway, what I want to do is to find a way to programmatically take the link [URL] (the first link in a search for Jessica Alba using baidu.com) and have it return the actual link, [URL] . That is just one example. What I want to do is not specific to Jessica but for using Baidu.com as part of my group of search engines in my meta search eneing project.
Maybe there is a way of using the WebBrowser class but I did not see a member that was the URL.
Maybe there is a way of using WebRequest and WebResponse.
