I tried doing something like this. When I changed the properties of the service to allow interaction with the desktop it changed the return value of SystemParametersInfo to 1 instead of 0, but i did not see a change to the desktop still as I do in a regular app.
Maybe it is because I have windows 7, try this for XP.

Hi everybody!
I am using Net.2005b.
When i used unsafe functiuon with fixed keyword in it , the watch window work not properly. There are ""Unable to evaluate expresion"" message for all variables.
The "Autos" and "Locals" windows are empty.
For example
namespace ConsoleApplication1
{
class Program
{
public int index;
static void Main(string[] args)
{
Program pr = new Program();
pr.test();
}
public unsafe void test()
{
index=10; //at this point watch window not work correctly
fixed (int* j = &index)
{
*j = 20;
}
}
}
}
What is the problem?

I want to know is this problem in beta version or only in my installed version of Net?

Is there a way to make a MDI or SDI application, which already have menus, like File, Edit, View, just like VC++6 does? Heavy job, creating the menus manually

If you are using VS.NET <= 2003 : No.
The next version will have that feature

Oh comon. It can't be that hard.
I takes about 5 minutes to get the base items in VS.net and attach all the handlers.

To test different cardreaders,I wrote a program to do the write/read data test.At first,copy a file of certain size form Harddisk to the cards,and then read the file form every card(s) and campare the data with the source file data.According to the capacity of each
card,I should choose comparative file size from a ComboBox,such as 1MB,32MB,64MB,512MB,1GB,ect.Amd what's more,I can not know what the number my user will input to the ComboBox.So,my question is:If there is a way to let me read 1GB(or some other number>1MB) data from a file(size more small and more better.)?
Thanks!

This makes sense.

Well. See System.IO. BinaryReader, FileStream... but it seems like you're looking for a
file-compare function in C#[^]

Hi!
Thank you!
//at present,before test,I must choose the
//sourcefilename which meet the proper size of the
//card to be test.The following code can do the right
//thing when I offer the correct sourcefilename.
......
FileStream sourcefile = new FileStream(sourcefilename,FileMode.Open,FileAccess.Read,FileShare.Read,4096,true);
File.Copy(sourcefilename,destfilename,true);
FileStream destfile = new FileStream(destfilename,FileMode.Open,FileAccess.ReadWrite,FileShare.ReadWrite,1024,true);
destfile.Seek(0L,SeekOrigin.Begin);
sourcefile.Seek(0L,SeekOrigin.Begin);
while (((i = sourcefile.ReadByte())==(j = destfile.ReadByte()))&&(i!=-1)&&(j!=-1));
if ((i==j)&&(i==-1))
{
mylusbs[threadnumble].Text = "PASS!";//currentlusb.text = "PASS!";
mylusbs[threadnumble].ForeColor = System.Drawing.Color.Blue;
}
......
? can you offer me a way to create 1GB file from 1MB file
Thanks!

I don't quite understand how the above code is related to creating a 1GB file but...
Use FileStream and write your 1MB chuck 1024 times. I guess that would work right??

Hi!
Yes,the code I showed you is not related to creating a 1GB file,and I wish you can change it and let it be related to creating a 1GB file.
1MB*1024=1GB.Yes,you are right.
So,what the code should look like?
Best Regards!

Hi~
WHat is the SqL Command for sql server 2000 wince which is used for rename a table of the database?

|
|

SQL questions should go in the SQL forum[^].
The answer is sp_rename. Its a system stored procedure. Check out SQL Server Books Online (installed on your machine). Also available on MSDN[^]

I really appreciate the emails from the code project members, concerning my unfruitful download of Borland C# personal edition.
I decided to delete it from my HD.
I would love to see for myself first hand, a program created in C# . I want to download it, try it,
just to see how it looks and feels. Can someone recommend a C# created program, that I can
download ? It can be about any subject matter. I just want to see it and try it out. It can be a quick little program , makes no difference what it's about.
Thanks again for the emails, I really appreciate the help.

A C# program can look and feel any way you want it to look and feel. You are not bound to using only the controls provided in the framework. There is a lot of C# code that can be helpful here at www.codeproject.com[^]. You can also visit www.gotdotnet.com[^].
Here's an example of a nice program created in C#: ASP.NET Web Matrix[^]
Trust me, .NET is the lastest and greatest things out there right now (unless you're doing driver developement or something that needs to be highly optimized). Almost everything is heading towards managed code.

Hello,
I wonder if there is a way to avoid events in a part of the code.
Exemple:
I use the event BackColorChanged of Button for some purposes.
And in a specific part of my code i also change the backcolor BUT i DONT want that the BackColorChanged event will be thrown.
Any ideas ?
Regards.

Well here's a quick hack: You can have a bool field to ingnore the next event. Reset the ignore field immediately.
if (!ignoreEvent)<br />
{<br />
}<br />
ignoreEvent = false;
Or you can derive from Button and fix whatever you are trying to do there.

Also, you could unsubscribe your event handler, process the specific part and then resubscribe the handler.
Event -= new EventHandler(handlerName);
Event += new EventHandler(handlerName);

Hi,
I using 5 radiobuttons in a GroupBox and 5 checkbox controls.
I looking to find wich index of the group of radiobutton and the index of the checkbox group
Can you help me ?

huh??? clearify.
The only thing I can think of is you might be looking for TabIndex for some reason. If you are looking for the one that is selected you need to check the controls by yourself.

I need to create a program that runs in the background. When this program runs initially, it instantiates several objects that must be used by other executable programs.
The problem is: How can I pass a reference of objects that I created in "Program A" to "Program X"?
Any help, greatly appreciated.
