Hi,
In one of my project, I have to capture the Image of a control which is not visible / focused.
I have to capture & display the images of the controls which are placed on the different tabpages.
The thing is I can capture the image of the control when the control is visible and the focus is set to the parent tab page.
I tried with various methods but no success. One of the methods I have used is “CreateDIBSection”.
I have also tried using CreateGraphics method of the control.
It will be helpful if the Source code is posted,
Looking for your help.
Thanks in advance,
|

There is no way I know of to get the image of a control that is not visible. Having said that, Vista seems to be doing it, but I suspect it's rendering an app in a smaller window, essentially moving it there.
If it's a control in your app, then you should be able to write a method, if it's a custom control, that renders the current state to a bitmap. Doing it for controls in your own app should be easy, think instead of trying to get a bitmap that doesn't exist, about the fact that you have all the state info for the control, you can rerender it where-ever you like.

hi,
how can i remove a tooltip from a control?
my problem is i have a textchanged event, that should set a tooltip to an picture box by:
toolTip.SetToolTip(targetControl, caption);
--> the tooltip change with the content in the textbox, so when i execute again the SetToolTip function a new tooltip will be created, but the old one is already existing.
thats why i am looking for a function to remove the old tooltip...

Hi,
normally, this should work:
<br />
private void textBox1_TextChanged(object sender, EventArgs e)<br />
{<br />
toolTip1.SetToolTip(pictureBox1, textBox1.Text);<br />
}<br />
I created a picturebox named 'pictureBox1' and
placed the above code within the text-change eventhandler
of my textbox 'textBox1'. Anytime I changed the text
the tooltip will be updated. There are no multiple
tooltips on the picturebox. Maybe try the method RemoveAll()
of toolTip1.
Regards
Erik

Set the "AutoPopDelay" property of ToolTip.

Ok, my problem is i even don't have any reference to the tooltip object.
|
|
|
|

i think it will be better if u create tooltip object runtime
and on the textchange event u can dispose the old tool tip object by
toolTip.Diapose() method and create new instance of tooltip object
and set it again.

Hi,
Yes ! Either you can open the text file using the IO classes provided in the .Net or you can directly open that file in notepad using Process.Start(). Have look here[^]

then you should open the text from within your program and display in a Read-only (or disabled) text control. You cannot open en text in notepad and somehow disable it from editing.
StreamReader srMyLogfile = new StreamReader("path/to/file.txt");
txtYourTextbox.Text = sr.ReadToEnd();
txtYourTextbox.Enabled = false;
srMyLogfile.Close();
srMyLogfile.Dispose();

What is the Assembly/Namespace for capturing Video in Microsoft's DirectX Manage Code using C# or VB.Net Language?

Add reference in your project to DirectX.Capture.dll.
This dll requires DShowNET.dll, make sure they are in same directory.

Yeah thats right, thanks a lot. I am just wondering whether this DirectX.Capture.dll and DShowNET.dll is from Microsoft or from Third party? Because it give dll-signing problem.
Thanks and regards

Hi All,
I want to use this property but in MSDN it says "This property is not currently supported and always throws a NotSupportedException.". When will it be supported? Can you suggest any other method or property?
|
|
|
|

This should work, pls try and let me know.
private m_NetworkStream = new NetworkStream();
public override long Length
{
get
{
return m_NetworkStream.Length;
}
}
Regards,
Bhupi Bhai

|
|
|
|
Should I put this code in my code? If it is so, "private m_NetworkStream = new NetworkStream();" it gives compile error.
Can you give detailed information please?

Friends,
Is it possible to generate source code (say for example C#) using Visio?
Thanks.

I really don't think so.
