View 1 RepliesI 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.

dataGridView1.DataSource = dalObj.GetRecords().Cast<TMPB_attn>().ToList();
dataGridView1.Refresh();

Can any C++ or C program save input data?
View 3 Replies View RelatedI'm a C beginner. I have questions, let say if I have a structure of message containing of Id, Length, and 3 bytes of data, and I want to manually saved in individual bits of data, how can I do that? I confused on how to use typedef struct and union. Below is the sample code:
typedef struct {
uint8_t Id;
uint8_t Length;
uint8_t DataField[3];
}AA;
[Code] .....
By the way, the DataField is declared as above. It's not necessary for a data to be 24 bits. It can be bit 0 - bit 8, it can be bit 10 - bit 15 and so on. So, for each case, I want to ignore the other bits.
I have to read a particular student data from file using his Roll no and modify it and then save it to file again
This is the File

how can i read data of roll no 35 and modify it and save it again to the file
this is my program
int r = 0 ;
while ( ar[j]!="0" ) {
//cout << "Salman majid is

so i have two classes ( main and another one ask ) in main i have defined 3 arrays (char drivers[250] ,offences[250] , owners[250]) and also included their pointers ( char *drivers_ptr,*offences_ptr,8owners_ptr)my problem is that i need to set values (actually 1 string of 250 chars to each of these arrays BUT from the class ask without making these arrays global -as this is prohibited by my university exercise !- )
so my question is how will i manage to save data to the arrays that i have defined in main using their addresses(through the pointers of each one that i have passed to the ask class) from the ask class ?
I'm trying to run so called student-administration program.I got functions that can read and write student data, but the one saving the data from about 30 students has some problem that I can't figure. (warning: I'm quite new to C programming)so this is the code:..I guess I can't use global variables as function arguments?
Code:
//global variables
static char ReturnName[31];
static char ReturnFirstName[31];
static float ReturnAverage;
}
[code]....

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...
I am having a lot of trouble trying to save and upload a data table from a text file ,the data table which is bound to a datagrid, creates its own columns at the formloading event, and everytime a user clicks a button row is added to the data table. With the loading i put this code which i thought would read a text file and put all the content my datatable however a exception pops up saying Duplicate Name exeption. Heres the loading piece of code :
{
string filePath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop) + "\DG1.txt ";
if(File.Exists(filePath))
{
StreamReader reader = new StreamReader(filePath);
string line = reader.ReadLine();

I'm working on my first own project which is to collect some info from a save game file and then parse it to a website. Skyrim uses a .ess file extension, which to my knowledge is a binary file. I know how to open a file for reading but how to extract the info I need from there. Do all games use a standardized serialization or can the format of this file be anything?
If reading the binary file turns out to be too difficult, would it be possible to hook the game and retrieve info that way? If so, where would you recommend to start learning that stuff?

I have this simple code:
#include<stdio.h>
int main(void) {
int mat[10][10],i,j;
printf("Enter your matrix
[code]....
This program ends up having a matrix made by the user ( in this case a 4x4). So my question is:
How do I save the user-made matrix in a text file? And how will i be able to reopen it?
I am creating a program using the inheritance. The superclass is person and subclass is employee,manager etc. I will prompt the user to choose which subclass he want to save the record to but i dont know how to write and display the record of different subclass to and from a txt file.
