So once I click browse I get something like "E:New Files" But there is this .log file in this folder which I want to automatically store in this path.
Right now I have to click on this .log file and then select open. Is there a way I can directly load the file.I have been trying to use the FileStream but no luck.
Is it possible with C# to get the default program for an extension? I've already done some research for it, but the only thing I've found out is a way to make my program the default program for an extension. So I my question is, is it possible to use anything similar to check if there is already an default program for an specific extension and which program is it?
I want to open a command prompt from a console application in a separate window and write some lines of text in the new command prompt.
In the Below code it is not opening the new cmd and not writing the text...
Here is the code: public static int Main(string[] args) { int retValue = 0; try { ProcessStartInfo MyProcess = new ProcessStartInfo(); MyProcess.FileName = "cmd.exe";
I'm trying to add a function now that lets the user open 1 or more files and import them to the database and dataGridView. Now the way it is now (should) work. But when it has finished with FILE1, it won't add FILE2 as it then gives me an error that the Column Date Already exists.
Is it possible to define and write your own file extension. if so is it an easy process or a complex waste of time. All I want to do is define a source file for a programming language I write.
I am trying to write a function that determine if a file in a directory is of a gif/bmp/png/jpg extension. Right now I think I have correctly written my code all the way up to listing the files in the directory and opening them in binary mode.
Now, I am struggling with figuring out how to determine what extension the image is. Right now i am just focusing on writing my "bool isGif();" function... To determine if a file is a .gif extension using binary, the first 6 bytes of the file will contain either GIF87a or GIF89a.So, to do this I would read the first six bytes of the file using the function below, correct?
fin.read((char *) &a_file, 6)
Then, once I read in the first six bytes how would I conditionally compare it to determine if it is a .gif? Would I just use
if(fin == "GIF87a II GIF89a) { \do something here }
If I don't assign the icon to my executable file (f.e. it's a DOS application), or I have some unknown extension in the file, Windows Explorer assigns the icon to this file.
Is there a way to somehow get this icon? Either from the registry or by any other means.
I have a problem with an extension DLL that has an exported function. The function is being exported ok, it is called by a Windows service. The Windows service is using the exported function, and everything works. I am trying to create a file with:
But nothing happnes however. There are no errors, the file is just not created. Also, if i try to call MessageBox() in the exported function, nothing happens as well . I have a .h file which exports the function with __declspec(dllexport) DWORD WINAPI functionName(), and also a .cpp file with the function definition. There is no main().

How to open a file and just print what is in that file on the screen. I though maybe I had the directory wrong but putting G: or G: give me the same result. When I select 1 it just goes to the next line and doesn't print anything.
Code: int getchoice(void) { int num; int choice; FILE* outputfile;
this is my read/write functions based the read from the last post! then went nuts with it! used the %19s%*s on the write to the file, solved all the probs on the read side! but any refining on this would be great. This is another program that i started with the forums, and started going my own direction!
I am getting an error when i try to open FILE which user must enter then program must open that file i an function and copy string from that file in other .
why this is looping in an error message. I am inputting the entire file name when I run the program and it just keeps falling into my "if(!inputfile)" statement. Let me know if there is anything I'm just not seeing.
So I'm trying to see if it fails, but if i change "Input" name would the computer just create a new file name of it for example if i change "Input" to "asdf" the computer is just going to create "asdf" how do i fix it.
I am writing to write a program and performs the following tasks
- Reading a file (txt file contains some temperature values) - Display the temperature values (contents of the file) - Calculating the average of the temperature values in the file. - finds the maximum and minim value of temperature in the file.
The program is user interactive and waits for the user input and process according to his input (choice)
I have managed to complete the program and covered all the expect except the error handling for file opening and reading, although I have managed to do it for the part one part (i.e for the choice == 1)
I can repeat it for the other choices (i.e for 2, 3 ) but I do not want to repeat the code and do it in a different function or do it once for all. While making an attempt I can not handle the rest of the program and all the program turns into a mess.
#include <iostream> #include <fstream> #include <iomanip> int menu(); int myChoice(char); char inputValidating();
[Code] .....
Need Error handling for file opening and Reading that is used once, So far I have managed to do it for choice 1
