Visual C++ :: CFileDialog Does Not Display File Name Correctly
Sep 13, 2013
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.

I'm very new to MFC & VisualC++. I'm using MSVS2010 Pro. I am trying to write/debug a simple form that saves and restores the content of some edit controls. It seems to work as expected, except the file saves only to the Project Folder, regardless of where I browse and select to save the file.
Code:
void CMFC_FileDialogDlg::OnBnClickedbtnsave() {
this->UpdateData();
CFile f;
//Kinda Correct, Works but still saves in Project Folder
BOOL b_OpenFileDialog = FALSE;//this doesn't act as bool in CFileDialog?
[Code] ....
My only experience is a little simple VB programming in Excel, so any specific examples??? Also, rules seem to change from version to version? I have to "update" a number of undocumented programs.

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.

In my attempt to capture multiple files using CFileDialog I discovered that there is a limit on the number of characters in the file name buffer. [URL]
I have used this code to get the file names and it works fine up to the point where the buffer is full. NB: m_vcsPathnames and m_vcsFilenames are std::vector<CString> types.
Code:
// get a list of the files to process
wchar_t szFilters[]= _T("All Files (*.*)|*.*||");
// Create an Open dialog; the default file name extension "*.*"
CFileDialog fileDlg(TRUE, _T(""), _T("*.*"),
OFN_FILEMUSTEXIST| OFN_HIDEREADONLY | OFN_ALLOWMULTISELECT, szFilters, this);
m_vcsPathnames.resize(0);
[code]....
Is there any possible work around for this limitation, other than completely writing my own CFileDialogExx class ?

I have subclassed CFileDialog. I need to select both file and folder on certain case only. Suppose I have a folder selected and it is containing desired file type. Then in such situation, On clicking open button will not open the selected folder. But just close the CFileDialog with IDOK.
For doing this I need to provide my own implementation for Open button handler. I am not getting how I can do this.

There was an "impovement" since Windows 7 in algorithm for selecting the initial directory, which is described here OPENFILENAME structure. Briefly:
Windows 7:
If lpstrInitialDir has the same value as was passed the first time the application used an Open or Save As dialog box, the path most recently selected by the user is used as the initial directory. Otherwise, if lpstrFile contains a path, that path is the initial directory.
Otherwise, if lpstrInitialDir is not NULL, it specifies the initial directory. If lpstrInitialDir is NULL and the current directory contains any files of the specified filter types, the initial directory is the current directory. Otherwise, the initial directory is the personal files directory of the current user. Otherwise, the initial directory is the Desktop folder.
The problem that this behavior is not what users of my program expect. Another constraint is that I need to use old CFileDialog dialog, not Common File Dialogs. I've tried to use advises described on StackOverflow and on MSDN. This solution by EllisMiller works perfectly:
Specifying a full path (including filename) in lpstrFile. The filename of course shows up in the filename box which is annoying. I ended up using a filename of "." and adding a bit of code to clear the filename combobox once the dialog is open.
BUT I can't figure how to clear the filename combobox. I've tried to add hook procedure, enumerate windows and clear text, but this didn't work for me. So, my question is: how can I clear text in the filename combobox of CFileDialog?

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

I am writing a program to display values from a data file as an image. But I can only get a blue screen. Here is a small program resembling my code. what I have missed? I only changed OnDraw function.
Code:
void CColorDisplayView::OnDraw(CDC* pDC) {
CColorDisplayDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
if (!pDoc)
return;
CRect rect;

I believe I set up everything correctly. I linked the library folder, the includes, and included the libraries needed. It still comes up with an error that it can't find the functions or something like that.
The error:
Do I need to include the DLL some way? I tried adding it to the build directory and the EXE directory, but it did not work. My code is just a small test.
#include <GLFW/glfw3.h>
#include <cstdio>
#include <cstdlib>

I have a program that's not doing what I want it to do. This is the assignment:
The nth term of the sequence of triangle numbers is given by, tn = 1/2 n (n+1); so the first ten triangle numbers are:
1, 3, 6, 10, 15, 21, 28, 36, 45, 55,...
By converting each letter in a word to a number corresponding to its alphabetical position and adding these values we form a word value. For example, the word value for SKY is 19 + 11 + 25 = 55 = t10. If the word value is a triangle number then we shall call the word a triangle word.
the 'words.txt' has a bunch of words in this format:
"ABSTRACT"
"YOUTH"
there's about 1000 words in that format.
And for any triangle words I find, I put it into another text file which I called triangle.txt.
Now for my program, it pulls the 'words.txt' file just fine but it doesn't recognize any of the words in the file as triangle words.
#include <iostream>
#include <fstream>
#include <string>
#include <sstream>
#include <cmath>
#include <cstdlib>
int getCharValue(char a);
double sum1(std::string name);

We are supposed to split this lab into 3 files a .h and 2 .cpp's. The code I'll be talking about is going to be directed at the main.cpp file. Basically we are supposed to be able to enter as many classes into the program and when you are done the program is supposed to save the contents into a .dat file. This lab is working off of an older lab so I already have a .dat file I am trying to test with this program by reading it into my program when I first run it I prompt if the user wants to load previously entered courses and if they reply with a 'Y' the program will load the contents of the .dat file. Problem is right now when I load from the .dat file only the first class is correct. Every other class after that is just giberish. I've tried everything but can't get the restore part working. I also cannot get the save to .dat portion of this lab working either.Here is my code:
#include "Course.h"
#include <iostream>
using std::cout;
using std::cin;
using std::endl;
using std::ios;

I have written an program to emulate a shopping list. Everything works fine, until I try to read in from a file. Here is my read and write code (the write code looks like it is working ok, but I figured I would include it just in case), and an example of what happens to a list that has been written, then read back in.
I took this list, and wrote it to a file, then read that file back in. The .txt file looks like everything was written out properly, but when I try to read that exact same list back in, this is what I get:

So I have a small program which is supposed to write and read multiple objects from a file, but for some reason it doesn't write the information when I use "fstream" to create the object from the fstream class, but it does when I use "ofstream". Also, it doesn't read the information from the file no matter if I use "fstream" or "ifstream". I watched a video where this exact code worked just fine, but it just won't work when I run it. I'm using Dev C++ 4.9.9.2, I don't know if that has anything to do with it, I also tried it with Code::Blocks, didn't work either.
Here's the code.
#include <iostream>
#include <fstream>
using namespace std;

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 need to write a function that displays the days of a specified month. I have been looking for sample code but haven't had much luck. Here are the guidelines for the function:
Write a void function named displayCalendarDays. This function is passed two input parameters. The first parameter is an int that represents the start day. Start days are numbered from 0 to 6 with 0 representing Sunday and 6 representing Saturday. The second parameter is an int that represents the number of days in the month. If the start day is not in the range 0 to 6 or if the number of days is not in the range 1 to 31, the program should display useful error message instead of displaying a calendar. If the parameters are OK, the program should display a calendar similar to the following:
1 2 3 4
5 6 7 8 9 10 11
12 13 14 15 16 17 18
19 20 21 22 23 24 25
26 27 28 29 30 31
After the last day of the calendar is displayed, the function should advance the cursor to the next line.
Note that for the display above, the start day is 3 and the numbers of days is 31.

I am having a strange problem trying to display a dialog from a UI thread. The dialog simply fails to display. I have a function DisplayFlashBox(), which creates the UI thread:
CUIThread* CIMUIHelper:: DisplayFlashBox(const CString &sMessage, const int nInstrumentUID) {
CUIThread *pThread = new CUIThread();
pThread->SetString(sMessage);
pThread->SetInstrumentUID(nInstrumentUID);
pThread->CreateThread();
[Code] .....
The dialog doesn't display. When I tried debugging, I found the OnInitDialog() method of CIMFlashBox class doesn't actually return. Very strange. I tried calling the DoModal() method instead of Create, but doesn't display the dialog either.

1.Create one 2-dimensional array. The array will consist of numbers from 1 to 10. And will also contain the number in words. Display the values of the 2-dimensional array.
Sample output:
1 - One
2 - Two
3 - Three
Paste the program code here:
2.Create a program that will accept two integer numbers. These integer numbers will be the limit of the multiplication table. Store the values in a two dimensional array.
Sample output:
Enter x: 3
Enter y: 2
