Hello
thanks for answering and forgive my bad english. I'm tring to do the following:
private void on_layout(object sender, ...)
{
int newwidth = this.width;
int newheight = this.heigth,
suspendlayout...
if(right side of button1 < left side button2 || newwidth > actualwidth)
{
actualwidth = this.width;
}
else
{
this.width = actualwidth;
}
...
}
the problem is the form borders are visible inside the form area , when i'm in the else block, trying to reduce the window size. that's the effect i would avoid.
I'm sure i'm using the wrong approach and i need some suggest to me how to solve this problem.
Thank you
S

You can set a minimum size on a form.

Hi,
I want to move MS Agent Character to a control like Button or PictureBox etc. But MS Agent takes Screen position to move. How can I get the screen position of a control dynamatally as user may resize the form and screen position of a control changes. First, I thought of getting the property named "Location" of a control but, Location varies if the control is within a groupbox or panel. Moreover, Location doesn't say Screen position.
Please help.
Thanks

Try the PointToScreen method of the parent control:
Point screenCoordinates = this.PointToScreen(button.Location);
I'm assuming the control (button) is owned by the form itself, if owned by a GroupBox for instance then it would be:
Point screenCoordinates = groupBox1.PointToScreen(button.Location);

I am currently generating an image in DirectX using things such as Line.Draw() etc. and I need to get the image out as a bitmap. I Have managed to accomplish it using SurfaceLoader.SaveToStream(ImageFileFormat.Bmp, _surface0); however, this is too slow, I need something I can do in real time. Does any one have any suggestions for another way to get the image from a DirecX surface to a bitmap?

I need to transfer large chunks of data ( audio data actually ) between two systems in a LAN. Which method would be more time efficient. Remoting or TCP.
Thanks a lot.
|

Definitely TCP (or UDP). Remoting has overheads.
Best,
Jun

Apples and oranges, i.e. not competing technology to weigh against each other, Remoting is a technology that runs on top of a TCP stack so performance wise you are always going to get better performance the lower down the networking stack you go at the sacrifice of convenience and safety.
I.E. tcp is faster but you have to write a lot more code yourself. Remoting is mostly applicable when you are working with business objects.

Hi
I have a tricky requirement for checking for a particular data existance in the Excel file on the Cell[m,n], this I should verify when ever I try to lauch any excel file then my application (addin or what ever etc., ) should look for this criteria for existence of the particular data on particular cell then open the excel file in EXCEL.exe application.
Does any body as any clue, on how to implement this. I tried some different methods by writing Excel addins using C# but the success is limited to controlling and customising the frame-work (Menu, Commandbar, ToolBar etc. of EXCEL.exe)and could not able to intercept the events of excel file and could not intercept the data in the excel file which is being tried to open. Here the excel file is not a particular file, this data existence criteria should work for which ever the excel files we choose to open.
Please share if anybody has any details on this, would be a definite help.
thanks,
-Ram.

IIRC unsafe code and pointers (Type*) aren't available in vb.net. The languages are almost identical, but there are a handful of features in each not supported by the others. C# has unsafe (dunno why it's not in VB), VB has optional parameters (depricated and only kept for legacy VB code support, but useful for writing com wrappers in any langauge), managed C++/C++Cli allow a more direct mixing of managed and native code (useful for high performance interop situations).

There are no equivilents. Unsafe code blocks and pointers are not supported in any version of VB/VB.NET to date. It doesn't look like they'll show up in the next release either.

Thank you. I've been programming with VB for a while now and am trying to decide if I need to pick-up C#. I have an application that has alot of images that need to be displayed an then manipulated quickly. I've found a ton of helpful articles on CP but there almost always in C#. I have a good C# to VB converter but it has been balking at these bits of code. Thanks again everyone.

It couldn't possibly hurt. For image manipulation, C# is just about a must, or a Managed C++. I know VB.NET and C#. My C++ is pretty rusty, but I can still read it and translate very easily. I do the bulk of my work in VB.NET, but use C# for the stuff that VB.NET doesn't support, like pointers and unsafe blocks for image manipulation. (Thank you Christian!)

Hi,
Tried to understand INTERFACE... got confused with Class. What is the basic difference between INTERFACE and CLASS that can be describe in one line ? Any good article ?
|
|
|
|
|
In C#, an interface looks like a class, but has no implementation.
Best,
Jun

An interface contains empty methods, properties, and events (and mabe some other things). When a class "inherits" an interface that class must implement all that is defined in the interface. Interface members must be public and the class "inheriting" the interface must expose all the interface members a public. Create a simple interface with a method or two and make a class that impliments it. Visual Studio 2005 can implement the interface for you if you tell it to do so.
interface AGetter
{
Stuff GetTheStuff();
}
class StuffGetter : AGetter
{
public Stuff GetTheStuff()
{
Console.WriteLine("Gettin the stuff...");
Stuff aBunchOfStuff;
...
returm aBunchOfStuff;
}
}
static int Sqrt(int x) { if (x<0) throw new ArgumentOutOfRangeException(); int temp, y=0, b=0x8000, bshft=15, v=x; do { if (v>=(temp=(y<<1)+b<<bshft--)) {="" y+="b;" v-="temp;" }="" while="" ((b="">>=1)>0); return y;

Hi Henize,
Thanks for your answer. It really made sense to me to get the idea about Interface. But I was wondering, what is the use of this Interface ? Why do I need that ?
Regards.

Interfaces are useful for specifying functionality for different classes, so that you can use that functionality without caring about the exact data type of the class.
For example data binding uses a data source that implements any of the interfaces IEnumerable or IListSource. That means that anything that implements any of those interfaces can be used as a data source, like an Array, a List, a Dictionary, a DataSet, a DataTable, a DataView, a DataRowCollection, etc.
