I don't understand - why do you need regex to match a constant string ?

Hi there,
How to change UI(e.g. Menus)Labels in MDI Form? I'm using Localization for Multilingual Support. It is OK in childForm When CultureInfo object set to CurrentThread.CurrentCulture and CurrentUICulture. I want to change language on the spot without having to reload MDI form.(For example when change language menuitem click).How can I do for that?
I would like to know how to handle in your application situation like this?
Thanks in advance.

Hi, i'm trying to draw on the desktop...made the following code from combination of stuff i found on internet
[DllImport("user32.dll")]<br />
private static extern IntPtr GetDC (IntPtr hwnd);<br />
<br />
[DllImport("user32.dll")]<br />
private static extern void ReleaseDC (IntPtr hwnd, IntPtr hdc);<br />
<br />
private void button1_Click(object sender, System.EventArgs e)<br />
{<br />
IntPtr deskDC = GetDC(IntPtr.Zero);<br />
using (Graphics g = Graphics.FromHdc(deskDC))<br />
{<br />
g.FillRectangle(Brushes.Green, 100,100, 100,100);<br />
<br />
}<br />
ReleaseDC(IntPtr.Zero, deskDC);<br />
}
The problem is when you drag windows over what you drew...windows erases. I could just dump the drawing into a thread or timer but thats wrong...i want to somehow listen to the desktop's windows messages and paint when it paints...any ideas?
|
|
|
|
|
hmm, i put the draw in a while loop and i didn't like the resuts...it draws everywhere...not just "over the background image" like i was trying to achieve.

Can anybody tell me how to make the application start with windows?
thanks a lot.

You have to create a key in the registry, in
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
They key name doesn't matter, but the key value must be the full path to your executable (try Application.ExecutablePath).
Use the Registry and RegistryKeys in the Microsoft.Win32 namespace.

I am writing a keyboard hooker for a study that I want to run. That study requires that the program run all of the time (as it is analysing all of the text that is input into the keyboard). As I am likely going to slow down the computer a lot on mere merit that I am putting a system wide hook on the keyboard, I have another question. Where should I be running the interpretation code from? I was thinking that I should likely run this as a Windows service but I would appreciate input. Thanks a lot,
Jim

Your hook procedure must reside in a DLL by itself. I recommend you put in this DLL the least possible amount of code, because it will be injected into every process.
It really doesn't matter (in terms of slowing down the computer) if your program (the one that installs the hook) is a service or a regular app, since it will only run once. But a service has de added benefit of capturing text while no user is logged on (eg. the logon sceen -- correct me if I'm wrong.)
I would reccomend writing your DLL in plain old C/C++ (without the .NET or MFC) because it (and the DLLs it requires) will be loaded into every process.

Thanks a lot, that helps greatly. Perhaps I should ask another question while I am at it.
I want to run some statistics on all of the text that I interpret. At what point should I do this? What I was thinking of doing was to simply keylog every stroke that comes my way and on a daily basis (or some other set time frame) run the statistic analysis from a windows service.
Here is my question:
At what point should my code commit the changes to hard drive? File IO is a pretty taxing process, so I was thinking that I should keep as much of the typed text as possible in RAM and commit them to some point on the hard drive as infrequentlf as possible. However, that poses another probem; As the code is injected into each process seperately, there will not be the consistency that I require. The text has to be stored in order.
How do I deal with this problem? Thanks a lot!

In Win32 (not .NET) there are ways to have shared memory between all processes. Well, at least there used to be. I'm sorry I can't be of more help because I never had to use them, and it's been several years since I last used the Win32 API (.NET is so cool!), but I remember memory mapped files to have this capabiltity (at least in Win9x).
You probably could get better results if you ask in the Visual C++ Forum.
Good luck!

Hey
not sure what you are using
to make an installation ?
But can you program in what you mentioned
into the installer ?
i know various installer creation programs
like installshield, wise etc
can create and modify registry keys etc.

Hi Sasuko,
.NET allows us to develop setup and deployment project's for installing our applications. The sttup project provide's different editors for customizing the deploment. One among them is the RegistryEditor using which you can add registry keys and values to be added on to the target computer.

Hi there,
I hava a Form with 2 UserControls and 1 dialogBox. I want to use the DialogBox to set which UserControl will display on the Form.
-UserControlA(a button: buttonToB)
Form -UserControlB(a button: buttonToA)
-DialogBox(2 buttons: Ok & Cancel)
The Form will display UserControlA as StartUp, when buttonToB is clicked, the DialogBox appears, if Ok is pressed, then UserControlA will be removed and UserControlB will be add to the Form.
I have public menthods in the Form as follows:
public void RemoveUserControlA(){
this.Controls.Remove(UserControlA) // remove B
UserControlA.Dispose();
}
public void AddUserControlB(){
this.Controls.Add(UserControlB)
}
In the UserControlA, when the buttonToB is clicked
private void buttonToB_click(){
if(dialog.Result == Ok){
Form f = new Form();
f.RemoveUserContorlA();
f.AddUserControlB();
}
}
Questions
1) How can I have some methods in the Form, and then invoke it in the UserContolA (i.e. public methods ?)?
2) How can I remove the Usercontrols using the dialog?
thanks.

Is there no (free) way to play MP3s in c#, without requiring that the user download lame.exe? I don't need to do anything fancy like getting ID3 tags or anything, I just need to play back MP3s - smoothly looping them.
thanks!
