that would work if i would just add a whole bunch at once.
But the output has to be real time, so it still draws the focus.
The code in question is this function, which is called at about 10Hz:
<br />
<br />
private void UpdateList(ListBox lstBox, string rsp)<br />
{<br />
int intIndex = lstBox.Items.Add(DateTime.Now.ToString("H.m.ssff")+": "+rsp);<br />
lstBox.SelectedIndex = intIndex;<br />
if(intIndex > lstMax)<br />
lstBox.Items.RemoveAt(0);<br />
<br />
}<br />
<br />
any other suggestions what to do?
i could use a text field too, but there i dont know how to keep the field from allocating more and more memory.
here i just delete all entries over lstMax's Value.

You sure you're using BeginInvoke[^]? Your incoming network traffic is most probably on another thread, so you must use Invoke or BeginInvoke to marshal the call to the UI thread.

i programmed the network traffic via asynchronous network traffic, so as far as i understand, i dont have to take care about threads with this anymore  .
|

I assume you're using BeginXXX and EndXXX methods. While you don't need to do any thread management, they still run on different threads, you have to use BeginInvoke/Invoke when you are trying to invoke methods on the UI.

How can i scan or find text in images such as jpegs? FOR EXample, I am going to find the word "Hello" in a letter scanned in JPEG Format.. Is there a way?
|
|
|
|
|
|
Yes. Actually I am working with an OCR application. The thing is it converts and identifies the characters or letters in a scanned document ans saves the identified or converted texts in a jpeg file. So i must read the text in the jpeg file. How is this possible?

Hi! I am trying to send digitaly signed message from my program via CDO. I used examples from site and MSDN. Message was delivered, but i ended up with mail client telling me "ASN1 tag: unexpected end of data". Can anyone tell me what's wrong?

Is it possible to make a custom dialog that implements features of standard dialogs. E.g. a custom dialog should have two FontDialogs (in two tab pages for example). How to use standard FontDialog to implement this custom one, in order not to make it from scratch.
|
|
|
|
|
FontDialog is using windows api this
Make the modification of it not easy as other .net class
but you can still inherit from it and override
HookProc Method to add your customization
For more info
FontDialog.HookProc Method[^]

change the icon in the resource then select your form en go to properties (F4)
there you can browse for the icon.
good luck.
No hurries, no worries.

You can Write somthing like
System.Reflection.Assembly myAssembly=System.Reflection.Assembly.GetExecutingAssembly();
Stream file=myAssembly.GetManifestResourceStream("EmbeddedResource.test.ico");
Icon myIcon=new Icon(file);
this.Icon=myIcon;
Note:You need To replace the following line
EmbeddedResource.test.ico
EmbeddedResource--->Your Assembly Name
test.ico------>your icon name

Thats a little vague, can you give more details about what you are trying to achieve.
At the simplest level. Create a new user control and cut and paste your Forms contents onto the user-control. Then you can use the user-control on the form.

I haven't tried this but in theory, you should be able to change your base class from Form to UserControl.
