I wanted to stop the user from having access to USB flash drive while my program is reading data from it.I thought i could do so by closing the explorer at the start of my program and reopening it at the end of it.C Code to close and reopen the explorer?Or how to ban access to the USB flash drive?
View 2 RepliesI 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?
program im creating that is a Mediastore. I have 3 forms one start form where you choose which form you wanna go to Lager or Kassa are the two choices. in these forms i have 1 listbox each that share the same Data. In my Listboxes i have objects of a class called produkts that consist of 3 variables Name,SerialNumber and Price. When i have added these objects to my listbox and they are showing i wanna be able to use my "go back" button to go back to my orginal form where i choose which form i wanna go to and then go to eather my Lager form or my Kassa form and the items are supposed to still there however that is not happening for some reason.

{
InitializeComponent();
}

View 1 Replies View RelatedI have created an application to burn my data files into DVD. The problem which I am facing is as follows:
Suppose I have a folder "Doc_Files" present inside "D:Data" location for burning into DVD. The correct behaviour of the application is, after writing the "Doc_Files" folder into disc, I have to immediately delete this "Doc_Files" folder from the "D:Data" location.
I am calling the DeleteFile() Win32 API for deleting those files which are present inside "Doc_Files" folder.
The files are getting deleted successfully but they are still shown in the same folder untill I do not terminate the application.
Till the application is up those files are still visible even after they are deleted. And as soon as I kill my application and refresh my data folder those files are gone, and the folder becomes empty.
I am making use of IMAPI interfaces and methods for burning process.
I have an application that Opens files with different extensions for viewing purposes only. I use MFC with Multi-Document template.
When I go to Windows Explorer in Windows 7 and right-click on Libraries - Documents, and scroll down to New, Explorer shows multiple links for creating new files with these different extensions.
My application does not create New documents. It just opens them for viewing purposes. In fact, I have disabled the New portion of the mainframe window.
My code includes:
EnableShellOpen();
RegisterShellFileTypes(TRUE);
I am at a loss as to what portion of my code would have placed these links into Windows Explorer!
Is there any way to prevent them from being created in the first place?
I'm making a small MFC module that should generate a report (formatted using HTML) and then display it for a user on schedule at 8:30 AM every day. Pretty straightforward stuff.
I compose my report and then save it as a local HTML file in the CSIDL_APPDATA folder. I then use the following calls to display it using the default web browser (Internet Explorer in this case):
Code:
//Error checks are omitted for brevity
CoInitializeEx(NULL, COINIT_APARTMENTTHREADED | COINIT_DISABLE_OLE1DDE);
ShellExecute(NULL, NULL, strSaveFileTo, NULL, NULL, SW_SHOWNORMAL);
This module is run on schedule from the Task Scheduler. (The task is set up to run when a user is logged on, which is all the time for that PC. It is never turned off, put to sleep, etc. That computer has only one user that is never logged off either.)
This works perfectly fine when I test it by setting the task a minute or so in the future. But when the actual task is supposed to run at 8:30 AM, when the user wakes the screen all they see is a blank Internet Explorer page. (Note that if someone refreshes that page by hitting F5, only then my report is shown on the screen.)
So I started looking into it:
1) I checked that the file is properly saved (before calling ShellExecute) by reading it back and by comparing it with the original HTML markup that I saved earlier. It's all correct there.
2) I then checked the power saving options. That computer is set up to show screensaver after 5 minutes and to turn off screen after 25 minutes.
3) The web browser that causes this issue is IE version 11, with the latest updates installed. The operating system is Windows 7 Professional.
And why is IE showing a blank page only when computer is running unattended?
Im having a problem with the below code within a console app, I am copying and pasting data across server locations, the copy works fine but it looks like the app wont close and I am left with the screen (Shown in attachment).

Consider the following code which closes an overlapped I/O serial handle during application shutdown.
Code:
Win32Com.CancelIo(hPort);
Win32Com.CloseHandle(hPort);
It works fine under .NET 2.0 but after switching to .NET 4.0 it crashes on the CloseHandle. Removing CancelIO doesn't work.
What the correct way is to close an overlapped I/O handle? And why is there the difference between NET2.0 and 4.0?
Currently I am trying to convert RGB to HSL. Everything is working but the saturation value. It is always close to the correct value (usually less than 10 off). For example:
RGB:(196,72,84)
HSL:(354,-46,52)
Correct HSL(354,51,53)
CODE:
double s=0;
double l=0;
chroma=max-min; //works correctly
//LIGHTNESS
l=(max+min)/2;
//SATURATION
if(chroma==0) {s=0;}
else {s=chroma/(1-fabs(2*l-1));}
s=s*100.000000;
l=(l/255.000000)*100.000000;
I've been doing some looking and this example seems like the common way to remove the close button on a wpf window. Other than catching the on_click event or using that example, is there no better way to disable/remove that button?
View 2 Replies View RelatedMy 'c' program reads each line of a .txt file, makes a few changes and then outputs the line of text (which are names). I want the contents to be sorted and did not want to bother writing my own sort. The program runs in a command prompt from inside a batch file for example:
sort | makelist.exe BluRay1.txt > sorted.txt
sort | makelist.exe Dvd1.txt >> sorted.txt
..etc..
I have to supply a ctrl-z manually to close the piping. I tried the following which did not work.
buffer[0] = 26;
printf("%c",buffer[0]);
//printf("^(z)");
fclose(stdout);
fclose(stdin);
I never got the above to work so I am avoiding piping and just do a redirect instead.
makelist.exe dvd1.txt > unsorted.txt
makelist.exe dvd2.txt >> unsorted.txt
sort < unsorted.txt > sorted.txt
..etc.
Just wondering if I could have gotten the ctrl-z thru the pipe using "C".
FileStream obj = new FileStream(System.Convert.ToString(row.Cells["Lec_media"].Value),
FileMode.Open, FileAccess.Read, FileShare.Read);
if (Startdate2 == JCM_NOW2) {

View 3 Replies View RelatedI recently upgraded my operating system from Windows XP to Windows 7 SP1 64 bit. We are using Visual Studio 2008 Professional Edition and Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production.
When I try to execute this code I am getting the below exceptions
HTML Code:

Where rsProcessLog is the CRecordset object using a successfully connected database pointer pDatabase
In 32- bit Debug version I get a message box at rsProcessLog.Close(); with the below text Debug Error

(Please Retry to debug the application)
In 32- bit Release version I get a message box at rsProcessLog.Close(); with the below text Windows has triggered a breakpoint in Test.exe
This may be due to a corruption of the heap, which indicates a bug in Test.exe or any of the DLLS it has loaded.
This may also be due to the user pressing F12 while Test.exe has focus.
The output window may have more diagnostic information.
The above code was a working code in Windows XP with the rest of the env remaining the same and it continues to run in Windows XP but not in Windows 7.

View 11 Replies View RelatedThis is more of a Application Design question, Let's say I have Form1(Login), this is opened from Program.cs, when the user enters details, the Event Handler makes a instance of a class, adds the data and stores the instance within Program.cs class.
So the best thing to do here, is to close the Form1(Login) and open Form2(Main) via Program.cs so that I can send the List<Login> object with my Login instance objects to said form. This form will remain open throughout the applications use as it's like the main GUI for all the programs functions.
When I close this form, I may want to save some information before the application is terminated, so I may as well store the Login instances in Program.cs anyway.
Main stepping stone: Multiple (usually around 3 max) users can login this system if need be, which will mean closing Form2(Main) and then opening Form1(Login) so that once Form1 is closed it can recreate the From2(Main) form and pass the new List<Login> to that form.
What's the best way to do this, at the moment i'm creating the Form2 instance like so:
//....
//Detect the Login form being closed
loginForm.Closed += new EventHandler(OnLoginClosed);
//...
//Open the main form when the login is closed
private void OnLoginClosed(object sender, EventArgs e)
[Code] .....
This seems like it will work and do the job, but is there a better and cleaner way? The List<Login> will be passed to Forms which are created via Form2(Main) as this information will be needed. It's just that ive been told not to use Forms for too much data containment.

View 2 Replies View RelatedI wonder, why before accessing a file we need to have it opened, and after finishing with it, we need to close it?
If FileA is already open by PtrA, PtrB won't be able to open it as well until FileA is closed by PtrA?
When PtrA opens a file, are any extra resources allocated by that action?
I have a class 'A' which is almost perfect for my needs. Class 'B' uses class 'A' I've now designed Class 'C' and Class 'D' and noticed that there is a good chunk of code in class 'B', 'C' and 'D' for using Class 'A' is duplicated. I've separated out this code in specific, standalone functions in each of the classes. Now I'm wondering where this code should go. At the moment, the functions are duplicated in the three calling classes (B, C and D). Placing the functions into class 'A' would break the single responsibility principle. Inheritance to add functionality would likely break both SRP and LSP. The one that seems that it may work is composition.
However, Is designing a complete class just for a few functions over kill?
Would it be valid for classes 'B', 'C' and 'D' to access both the new class 'E' (which would depend on A) and the old class 'A' (which would have to be the same instance as the instance in the new class 'E'), or should the new class 'E' provide sufficient functionality so that Classes B, C and D don't need to access Class A directly? It would seem that its then an incomplete interface of the original object with additional functionality (ie, incompatible) Or should I do it a completely different way?
