I want to use a normal dll that contains a simple class and I want to create an object of that class in my C# code.

I'm not sure if you can do that, because I don't believe you can use p/invoke to export a class from a C++ dll.
Why don't you want to use managed C++ ?

I am not having detailed concept of that but now I am starting managed C++. Could you give me any links about it?

Nish has written heaps of articles about it, and has a blog as well, I'd read those.

Hi,
How do you add a new line to a textbox like in the following:-
<br />
textBoxMemberNotes.Text = File.ReadAllText(filename) &CrLf +now;<br />

|
|
|
|
textBoxMemberNotes.Text = File.ReadAllText(filename) + Environment.NewLine + now;
---
b { font-weight: normal; }
|
|
|
|
|
I just new it would be easy BUT do you think I could find a reference to that anywhere on the net 
Thank you

Ah yes - but if you know what terminology to search for then you probably don't need to search for it

first set the multiline property of your text box to true.
Then try this:
<code>textBoxMemberNotes.Text = File.ReadAllText(filename) + "\r\n";</code>
Hopefully, this should work.;)

Here's a simple example to get you started:
TreeNode selectedNodesFirstChild = this.treeView.SelectedNode.Nodes[0];
Just Google it.

Hi,
If I have some unnecessary Using Statements at the top of my cs code file, will that increase the size of assembly ?
|
|
|
|
|
No, they are ignored by the compiler.
|

|

No, they "only" allow you to use the types from a namespace without the need to specify the whole namespace. So for example you can write FileInfo instead of System.IO.FileInfo.

i want to make sth like sound recorder, record the voice and play it .
how could i do ?
|
|

Hi Nafiseh,
I found one complete demo Project in C# somewhere in the internet (I forgot) for Sound recording and playback. It is only 49KB. If there were any option to upload attachment file in this forum, then I could attach that for you.
If you are interested, you can email me from the email Link of this message, I will reply you with the ZIP attachment.
Emran.

Hi Emran,
I received the code, that works fine, thanks for that.
Now, one more question,
I want to send the voice over Internet, how do i get the buffer of the sound?
so that i can send that over internet to another connected user.
It would be great if you could send some links or code for the same.
Thanks & Regards,
Pramod

Hi Pramod,
Nice to hear from you and happy to know that the code is working fine for you.
Ok, as you saw that this project uses QaurtzLib.dll to do all recording and playback stuffs..etc..
As long as this library is not giving you interface to read real time Byte[] Stream, I dont see any way to
buffer the byte[] stream for LIVE transmission. I think you will have to save the recorded file first and then
read the binary file as byte[] stream and transmit over internet.
But another way you can do that (i am not sure if that is an efficient way or not at all..),
You can split the recording process for very short time like sampling and save the voice file and at the same sampling rate
you can read the saved file as byte[] stream and transmit over internet. You can try...
The best efficient way is to look for a library (may be free or commercial whatever you can get) who gives you LIVE byte[] interface
for the recording voice.
Feel free to let me know if this idea helps you or not.
Thanks
Emran
