Jun 11, 2013I'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...
C# :: Save And Upload Data Table From A Text File
Jul 12, 2014I 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.

Visual C++ :: Unable To Save File Using Cfiledialog Save As In MFC
Nov 5, 2013I 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();
}
This is the function code for me to add data inside database,it can run but just still cant save.

Mar 18, 2013I'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.

C :: Save Data To Arrays Defined In Main Using Their Addresses
Dec 30, 2013so 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 ?
C :: Save Data From Global Variable Into Linked List
Jul 6, 2013I'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;
}

incompatible types when assigning to type 'char[31]' from type 'int'
C/C++ :: How To Deserialize Save Game Data (specifically Skyrim)
Jul 29, 2014I'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?
C++ :: How To Save File Directory To Text File Using Ofstream
Jul 22, 2013I'm having a little problem with std:fstream - in my program, the user selects the location of a file which I want to remember. So, I have something like this:
Code: std::string fileLocation;
//Code here creates an 'open file' dialog box which lets the user choose which file to open.
//The string 'fileLocation' now contains the path to the chosen file.
std::ofstream prefs("prefs.txt");
if (prefs.is_open())
{
prefs << fileLocation;
prefs.close();
}
This works fine if the file chosen is in the same directory as the program, however, if they try to choose a directory outside of where the program is kept, it saves the text file into that directory instead of the same one as the program. So, it looks like outputting a directory into an ofstream actually changes the location to which the file is saved.
Is there a way to save the file directory to a text file using ofstream and still have the text file save in the same directory as the program?
C++ :: Create Save File For A Game That Is Not A Separate File?
Oct 10, 2014How do you create a save file for a game, that is not a separate file? Specifically I am using code::blocks and sfml 2.1 to make a game and it saves to a text file at the moment. My problem is that it is very easy to modify the text file, and it is annoying to have to copy and paste several files if you want to use a copy of the game. I have a feeling that it may be to do with resource files, but I'm not exactly sure how to get these to work or whether you can modify them dynamically.

C :: Create A File And Save Text In It In PDF Format
Feb 13, 2014My 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."
