i used keyhook...and i got some time this error
CallbackOnCollectedDelegate was detected
Message: A callback was made on a garbage collected delegate of type 'Cyber_Client!Cyber_Client.Utilities.globalKeyboardHook+keyboardHookProc::Invoke'. This may cause application crashes, corruption and data loss. When passing delegates to unmanaged code, they must be kept alive by the managed application until it is guaranteed that they will never be called.

Bah. No. I wrote the solution, but instead I just remembered I was the guy who told you about that article, warned you that you will get that error and where to find the solution. Instead, no.

All your posts have been about malicious desires, disabling keys, disabling taskmanager, killing all processes. Why don't you give up already.

I apologize if this is in the wrong forum, but I was just wondering if there's any sort of keyboard short cut to force child windows of a program to the front. I was working on some data in a child window, and another program popped up for some reason. I went to click back to the program I was using and the main window popped up with the child window I was working in behind it. Anything I click on in the parent window just makes a "Ding!" because it's waiting for input from the child window, which is hidden. Alt+Tab does nothing. All I can do is shut down the program and lose the data I was working on. It's pissing me off.
Please, help, if you can. Thanks in advance.

There is no magic shortcut for that unless the application you're using exposes such functionality. Alt-Tab will switch between applications, or anything else that shows up on the TaskBar. I would say that you have to either move the parent window before working with the children or move the child windows after they appear. The best solution would be to go back to the manufacturer of the app and asks them to fix it.

someone should tell microsoft how to fix this - I'm sick and tired of having visual studio (2005 and 2008) open a modal dialog behind the main window, and not let me bring it to the front because the main window has lost focus and is refusing to budge. Anyone else grown to hate that 'donk' sound it makes when you click on it and nothing happens?
The only way out is to press escape, but that doesn't always work either; then the only thing to do is kill it in process explorer. Task manager can't do it, it's too polite, and vs says 'can't close because it's waiting for input'.
Does it still do that in VS2010? I'm hoping that with the switch to WPF, the entire gui will have been overhauled too.

What? I've never had it happen, in VS2002, 2003, 2005, 2008, or in 2010.

it's a common occurrence for all the developers where I work
I think it's TFS (and before that, VSS) integration that does it
I've tried installing various hotfixes from ms, and they don't help

how to store the image in folder and retrieve it and display it in picture box in stand alone application
|
|
|
|
|
You will have to embed the image into the applicaiton as an 'EmbeddedResource'. After which you can assign the image to a picturebox through reflection. To guide you in the right direction, look into the following class/method.
System.Reflection.Assembly.GetManifestedResourceStream("relative file stream, look up documentation")

Hi Everyone,
I am developing one windows application. In that application i'm using one webbrowser control to navigate web sites.I want to close that browser after some time.[Meaning I am accessing one web site after some idle time i want to redirect to login page.].
Thanks in advance.

Hi,
how about launching a System.Windows.Forms.Timer, and when it fires have it call myWebBrowser.Navigate()
to the page of your choice? (don't forget to stop the timer!)
|

Hi,
You are correct. for navigating purpose i'm doing same thing. whenever timer interval elapsed it will fire and it will redirect to login page.
It is redirecting to landing page. But still session is maintaing.
Suppose one user is logged into the site, Without logging out he left that one, after some time we are redirecting to index page.
There some other users can able to see his/her personal information.
[This problem is happening with the sites like codeproject.com
In codeproject.com they are using loginpage as well as welcome page is same.so that time it is giving problem for me.
]
Is there any way to kill that session information.
Regards,
Sekhar Reddy

I am unaware of any WebBrowser method that drops a session.
I would consider removing the WebBrowser and starting a new one.
|
|
|
|
|
I have tried to destroy the WebBrowser control and again i'm creating new instatnce of webbrowser. Still it is maintaing the session values.

I have an application which renders fonts in textboxes so the user can see what they look like. I then need to be able to delete that file. But when I try, I get an error because the file is locked.
I have figured out that if the textbox is never rendered to the screen, no lock occurs (so it's not the pfc or ff stuff, nor is the file read-only) (also, once I stop debugging, I can delete the file manually).
The Kicker: Only certain Fonts do this. bajoran.ttf gets this error, but TKDS9HOL.TTF does not.
Here is my code. Anybody have any ideas?
------------------------------------------------------------------
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO; //manual add
using System.Drawing.Text; //manual add
namespace FontFileTest
{
public partial class Form1 : Form
{
string strFile = "bajoran.ttf";
//string strFile = "TKDS9HOL.TTF";
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
PrivateFontCollection pfc = new PrivateFontCollection();
pfc.AddFontFile(strFile);
FontFamily ff = pfc.Families[0];
txt.Text = "Sample";
txt.Font = new Font(ff.Name, 12, FontStyle.Regular);
txt.Visible = true; //remove this line, will not lock
ff.Dispose(); //irrelevant
pfc.Dispose(); //irrelevant
}
private void btnDelete_Click(object sender, EventArgs e)
{
//extra stuff to try--irrelevant
txt.Font = new Font("System", 12, FontStyle.Regular);
txt.Dispose();
Application.DoEvents();
this.Refresh();
try
{
File.Delete(strFile);
}
catch (Exception exp)
{
MessageBox.Show(exp.Message);
return;
}
lblStatus.Text = "Deleted";
}
}
}

Umm, this might be a stupid answer, but are you sure that case-sensativity can't be causing that bug..?
|
|
|
|
|
I did actually think of that (and tried some stuff), but no, that did not make a difference.

Run the app as administrator? Make sure you have delete privs on that file?
