So in the first one what you mean is that i draw the titlebar close button etc with GDI?

Yes... you can even create your own controls that look and behave like the title-bar.

Hi,
I am looking for some help in integrating my UI designer with Visual Studio. The idea is silmiar to VS Class designer or Entity designer.
1. when the file is select, the designer is open.
2. it updates the file when the visual elements are changed.
3. it generates source code file. One visual elements represents one class. When the visual elements change, the source code also change accordingly. for example, the element is renamed, then the class name is changed and all reference are changed automatically like renaming a class in Visual Studio.
Any information is appreciated.
Thanks
Carey

Hi, instead u can create ur own designer that will accept name and type and location, those u can save to XML,DB. and afterwords u can draw the form at runtime as u want. even u can change the design of form at runtime via refreshing the XML or DB.

No.

No, in fact it's worse.
Strings are immutable. This means once they are created they can't be changed.
The first line creates an empty string.
The second line creates a new string from your two literals, and assigns the variable to this new string.
If you're very lucky, the compiler might optimise the extra creation out as it's not used, but even then your left back where you started with just 1 creation.
Just do it the normal way.
String myString = "test";

System.String is immutable, which means once they get created, they cannot change. Every new assignment results in a new string being created and the reference to the new string object assigned to the variable.
Those constructors exist to assist you in creating strings from already created char arrays, etc.

As the others have said, there is no benefit - in fact yours is about as bad as it can get, as it creates up to 4 strings:
1) new string(new char[21])
2) "{0}"
3) "test"
4) strTemp = ...
It may produce four if it doesn't "spot" that string.Format("{0}", "test") is the same as "test". Optimisation will almost certainly reduce this to one, but it makes your code look like it is written by a beginner, whether you are one or not!

Yes, but not if you're just going to throw it away in the next line.

Hello!
I'd like to create little system for mobile phones which can recognize speech. There are two ways to do it, first is to have speech recognition on mobile phone (however I've got difficulties with using PocketSphinx, if you'd like me to, I can explain what exactly), the other is to have speech recognition on server and just have mobile phone connecting to that server with the use of Skype. The communication between devices and applications would be as follows: Skype on mobile phone calls Skype on server -> Skype on server redirects the speech (with the use of server application) to speech recognition engine Sphinx4 -> Sphinx4 recognizes the speech and answers to Skype (do I need to do it through the server application?). Recently I've been working on creating acoustic model for Sphinx4.
I have already found some good code which I can use in my application: http://forum.skype.com/index.php?showtopic=260361&st=0&p=1158301&#entry1158301 . However I don't have the experience in writing server applications. (I've got some experience in C++, Free Pascal and Visual Basic but I'm rather newbie in C#). Can you suggest me how to begin with writing this server application? I would appreciate it if you can give me some useful materials to read, tutorials or advices.
Greetings!

Hi folks...
hope someone can help. I created a simple UserControl in a C# Project (VS9) that basically consists of a Label placed on that Usercontrol.
The following happens:
1) place the Usercontrol "Label" via designer on another UserControl "Parent"
2) change the Fontsize of "Label" to another value (e.g. from 9,25 to 14,75)
3) see the "Label" Control is relocated from original position to a new position on "Parent".
It seems to me that the control is relocated due to some scaling issues but I can't figure out what exactly is the problem. I am sure it is no big thing, I need the Usercontrol "Label" to stay in place instead of beeing relocated automatically in design view. Any ideas?

Check out the "Anchor" property.

I already did. Does not change behaviour.
I also have set "Autoscalemode" to none everywhere I could find it... still same behaviour. Running out of options...
Another funny thing is that the relocation of the "Label" usercontrol is done only once (according to the size I enter, the Location of the usercontrol "Label" will be set more down and right on screen if the Fontsize is larger). After it is done I can change fontsizes just as I want (even 100f)... the "Label" Usercontrol will no more be relocated by designer.
So this behaviour just shows if placing a new "Label" usercontrol on the "Parent" usercontrol and then changing the fontsize of the "Label" uctl. Strange in deed.

I have 1K tag. I have data of 1433 byte to be stored in the tag. Can any body help me for some compression technique to compress the number of bytes for the same information.
Thank You

It depends on your data. What is your data? More importantly, what is the entropy of your data?

If you can use entropy, please do so, the world would be much better of with an entropy reduction.

A hardware engineer I used to work with suggested a data compression technique that "removed all the zero bits, as they don't mean anything anyway". I wish it would have worked...

Good one
He (she?) should have a chat with jules Gilbert (you know, the persistent "magic compression" guy who refuses to ever let his technique be put to the test) on comp.compression 
|
|
|
|
|

Ok, that's a very ineffective way (Deflate is not bad, but the implementation doesn't compress that much at all)
If you want better results, you can look at SharpZipLib[^]
