Hy,I have a bing problem. I am developing an application that refreshes itself very-very fast, this is why I am using manual double buffering for drawing(i.e a memory graphics). I want to develop my app at design-time,that is why I place a lot of controls on the form(they all have an Image that they want to display).
But I need to draw them all in one place(i.e Form.OnPaint()).
How can I completely remove paint messages sent to the controls, and still give feedback to the form, whenever a control receives a paint message?
I need something like this:
Control.Onpaint()
{
//tell the parent that it should ask me for my image and draw it
//validate my update region,sa I don't get paint messages until I am invalidated
}
If anyone can help me..thank you in advance, it's a big problem for me.

Well..this doesn't help me as i need to use the same double buffering at design-time and run-time. First, Visible is always true at design-time you can't set it to false. Second, if i don't draw all the controls in the same place, I can't toggle from Visible=true\false,as transparency for the control(this.BackColor) means what's under all the controls(i.e. the background). I wan't the controls to look at design-time like layers.
Again..I need the controls to do no painting at all..the form does everything in one place

I have absolutely no idea what you are asking here. I have read this post multiple times, and cannot for the life of me figure out your problem. Do you think you could restate the problem another way, and additionally give a broad overview of what you are trying to accomplish? Thanks,
Sounds like somebody's got a case of the Mondays

Please read my answer in the upper thread..I accidentally started 2 threads.Sorry

This sounds like an absolute disaster. You want to add a layer where the controls paint event sends a message telling someone else to paint it ( which you can do just by handling the paint event BTW ), and you think this will make it faster ?

Sorry,I didn't give all the details. My controls are all image-based, but I wan't to also use them as sprites(I'm developing 2D games). I can't use the control's painting, because I will never get rid of flickering. Now..the form in it's onpaint already has access to all this control, so it's not hard to call child.GetImage() for example. That is what manual double buffering means..all painting is done in one place(form.onpaint)
I don't now how to stop the controls from using their default-painting.
Here is what I have at this moment for the control:
<br />
public class MyControl : Control<br />
{<br />
...<br />
private bool visible = true;<br />
<br />
public bool isValid;<br />
<br />
...<br />
public Image GetImage()
...<br />
protected override void OnPaintBackground(PaintEventArgs pevent)<br />
{<br />
}<br />
<br />
protected override void OnPaint(PaintEventArgs e)<br />
{<br />
isVisible = false;
Parent.Invalidate()
ValidateRect(this.Handlde) <br />
}<br />
Now..this is what the form should do:
<br />
public partial class TestForm : Form<br />
{<br />
...<br />
protected override void OnPaint(PaintEventArgs e)<br />
{ <br />
for (int i = Controls.Count - 1; i >= 0; i--)<br />
{<br />
if (Controls[i] is MyControl)<br />
{<br />
if (!((MyControl)Controls[i]).IsValid && ((MyControl)Controls[i]).GetImage() != null)<br />
{<br />
grafx.Graphics.DrawImageUnscaledAndClipped<br />
(((MyControl)Controls[i]).GetImage(),<br />
((MyControl)Controls[i]).ImageRect);<br />
((MyControl)Controls[i]).IsValid = true;
}<br />
}<br />
}<br />
grafx.Render(e.Graphics);
}<br />
Using this code..will invalidate the form continuously... blocking the form
What have I left out?
If I don't make MyControl derive from Control will not give me design-time support..but Control
implements IWin32Window so it get's messages fron the system..not the form.
Thanks very much for your patience..sorry I'm not very good at explaining

OK - moving controls around to represent the characters in your game is the point at which your design is broken. Fix this, and I'm sure you'll find everything works just fine. Even then tho, getting a good framerate without using DirectX is a challenge.

Well..most of the time I don't move them around, I just alter the control's image.
I know that control's might not be the best choice..but if I take out the control's painting,it would just be a container for my images + it keeps track of all thoe mouse\keyboard events.
If I don't use controls,it's easy, but I might as well develop my games in..Notepad

Use the formatting options in ToString():
j.ToString("000#");
|
|
|
|
|
similar to "X4" there is also j.ToString("D4");
|
|
|
|
|
Take your pick from the following (result == "0010" in all cases)...
int j = 10;
string result;
result = j.ToString().PadLeft(4, '0');
result = j.ToString("D4");
result = j.ToString("0000");
result = string.Format("{0:D4}", j);
result = string.Format("{0:0000}", j);
Sounds like somebody's got a case of the Mondays

not very good for [-99,-1] tho.

What, you don't think he intended to have "0-99" as one of his integer strings? Yes, but in an if statement, (0-99) == -99, so I think this is exactly what he was looking for!

Hi,
I have a xml file.I am trying to display the specific contends in a list box. for example::this is my xml contend.In the below items i want my list box to display only whatever is in "connection name".
connectionname>Anet
subnetmask>x.x.x.x
defaultgateway>x.x.x.x
dns1>x.x.x.x
dns2>x.x.x.x
dns3>x.x.x.x
dns4>
<con>
connectionname>BL
subnetmask>x.x.x.x
defaultgateway>x.x.x.x
dns1>x.x.x.x
dns2>x.x.x.x
dns3>x.x.x.x
dns4>
/con>
My code is displaying the full contend.
XmlTextReader textreadobj = new XmlTextReader(@"C:\Documents and Settings\j\My Documents\Visual Studio 2005\Projects\InternetApp\InternetApp\XMLFile1.xml");
textreadobj.Read();
while (textreadobj.Read())
{
lstProvider.Items.Add(textreadobj.ReadString());
}
So how can i make it display the items in connection name only.
Thanks in advance

string sPattern = @"[^\p{Cc}\\r\\n\\a\\e\\b\\t][\S]*[\w\p{Po}\s-`\p{Sm}]*[^\p{Cc}\\r\\n\\a\\e\\b\\t]";

}//end (finally)
input string is :-- \r\nloadplayer "playername=test_1"\r\n
output string should be :-- loadplayer "playername=test_1"
want to neglect all newline,tabs.. etc from the input string.
Now its doing fine, but also removing "r,n,a,e,b,t" from the starting of the input string.
Means, if the input string is:-- roadplayer "playername=test_1"\r\n
output becomes:-- oadplayer "playername=test_1"
it should be:-- roadplayer "playername=test_1"
so, tell me what i should do for better working.
Thxx...
Enjoy!!

The 'escape characters' are all in the format '\x'.
\n is new line... etc.
'\\' in a string represents a '\', a single '\' will look like an escape character.
So you need to use: \n \r etc instead of \\n \\r.
I've never use Regex before but I assume this is right.
Hope it helps.

Hi!
I've asked a similar question some time ago, but unfortunately without usable results, so I try again.
I put some text into the clipboard and want to trigger a paste action inside a terminal server session (i.e. programmatically do what happens when you press Ctrl+V inside a mstsc window).
Yes, I know that you can't programmatically see the different windows inside the WTS session and that the currently active application will be the target for my paste, but that's exactly what I want.
So far I tried using SendKeys, P/invoke to SendInput and keybd_event, posting WM_PASTE or even WM_KEYDOWN and WM_KEYUP with the exact parameters Spy++ reports, but I can't get it to work.
The first 4 ways simply give no visible result at all, with WM_KEYDOWN/UP I get a plain "v" instead of Ctrl+V.
Does anyone have any further idea?
Regards,
mav

Like this?
SendKeys.SendWait("[Clipboard content here]");
or like this:
SendKeys.SendWait("^a^v");
If you've tried the second one, it wont work - as you probably have noticed. Console windows doesn't accept pasting of text. Try getting the content of the clipboard somehow, store it in a string and then write it out like this:
SendKeys.SendWait(clipboardContent);
