Visual C++ :: Unable To Save File Using Cfiledialog Save As In MFC
Nov 5, 2013
I am trying to develop a GUI using MFC, but I am having trouble using CFiledialog to save a file. The problem is, the file is not getting saved to the folder when I use the CFiledialog. Below is the code I am using.
Code:
CString szFilter = "XNRep Files (*.xnrep)|*.xnrep||";
CString s = "xnrep";
CString t = "";
CFileDialog fileDlg(FALSE, s, t, NULL, szFilter);
if(fileDlg.DoModal() == IDOK)
{
std::ofstream file;
[Code]....
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 this code, where I capture window and make copy to bitmap of it. I am working on rotation of bitmap. But my problem is that when I save the image to file the result is just a black screen. It looks like there could be some problem either in GdipCreateBitmapFromHBITMAP() or GdipGetImageGraphicsContext()
How to fix it and to get the rotated image?
Code:
// CODE 81 and 82 de facto no difference
#defineCODE85 // 81
#defineWINDOW_MIN_HEIGHT200

I am trying to store each value of a column from a text file into an dynamically allocated array, which needs to be globally declared for further usage in the program.The input textfile contains the following:
34932 13854 13854 2012-01-07
172098 49418 53269 2012-01-07
I have written the following code:
Code:
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
int main()
}
[code]....
The commented printf line gives the entire values of the column, which proves that the file is correctly being read.But on compiling this program I get both compiler warnings and finally segmentation fault.

I 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 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.

I haven't seen this before but on Windows 7 Home Professional and VC 2012 in one particular app, a CFileDialog displays only the rightmost 11 characters plus the extension of the default file name. The rest of the name is there and you can scroll left in the file name edit to display it all, but initially the text is shifted left so it doesn't all display.
Code:
CFileDialog dlg(TRUE, "csv", strFileName, OFN_OVERWRITEPROMPT | OFN_HIDEREADONLY, "Comma Seperated Values Files (*.csv)|*.csv|All Files (*.*)|*.*||");
strFileName can contain anything and it will do it. Even a string literal will do it.

My objective is to create a file and save some text in it. But the twist is that file should be created in pdf format.
I have written following code:
Code:
#include<stdio.h>
Code:
int main() { FILE *fp;
char ch;
fp=fopen("file.pdf","w");
fprintf(fp, "%PDF-1.3"); //to initiate data storage in pdf file
printf(" Enter data to be stored in to the file:");
while((ch=getchar())!=EOF)
putc(ch,fp);
fclose(fp);
return 0;}
Now my file is created in pdf format, but when I open it by double click on it, it is not open and gives the message like: "Error in opening document. This file is damaged and could not be repaired."

I have this file that I would like to read into a multidimenstional array in c#: file. If I take the first set of lines as a first example, I would like the print_r to look something like this:
Array (
[SiiNunit] => Array (
[0] => Array (
[nameless.2BB8.4FB8] => Array
[0] => Array (
[bank] = _nameless.2917.43B0
[player] = _nameless.2813.6928
[companies] = 312
[code].....
this (as I expected it to) wrote each line of the file into a 1d array however, I would like it to write it to a multidimensional array.

I need to do a code that gave me Original string, uppercase string, lowercase string, reverse string (if letter is upper then convert to lower, and if lower then convert it to upper) and uppercase first (first character of each word in uppercase).
I need to do it in functions but i dont know hot to use strings. The program should provide the option to save the outputs in a file.

I'm trying to read from a header file to take the image dimensions and other variables but I don't understand how to iterate through the "key" so it saves each line.
This is what the header file will always look like:
!INTERFILE :=
!imaging modality := nucmed
!version of keys := 3.3
;
!GENERAL DATA :=
[Code].....
Ideally it would just skip the keys that aren't wanted and keep moving through the lines. Should there be a for loop for the key (and if so, how does that work with pointers?) or should this method just be scratched...
