Do you know SQL? If you don't then don't even start.
No one will help you with that kind off questions.
If you'ld like an answer, make sure that you show you've tried several options yourself or at least tried to find it yourself.
Nobody will give you code either, they'll only give links to where the solution could be.
if you want to start on databases (only if you know sql) go to MSDN or here on cp and search on ADO.NET, dataadapter, sqlcommand, connection, oledb, odbc, sql (last three depending on the kind of database), datasets, datatables, ...
That should get you started in a good direction.
good luck, but I doubt you'll make it...
(PS: out of curiosity, you do know SQL right?)
Coulda, woulda, shoulda doesn't matter if you don't.

I'm sure that more than one CP'ian would be happy to charge you or your company for the above mentioned code 
No one is going to do your job for you for free...

Just out of curiosity, why did you get put in charge of making a C#/database app if you have no experience with C# or databases? 
Best of luck,

I a calling an API method which requires passing the reference to an array as parameter. The problem is with that parameter
The actual function is
BOOL __stdcall G3BlockScan(int hRadio,<big>DWORD *Freqs</big>, int Count,int StopSquelchRaw, DWORD FeedbackTime,HWND WinHandle,DWORD Msg);
Here Freqs is an array whose contents are mofied by the The API function call.
I have wrapped this function in C# as follows..
[DllImport("wrg303api.dll")] <br />
public static extern bool G3BlockScan(int hRadio, <big>uint [] Freqs</big>, int Count,int StopSquelchRaw,uint FeedbackTime,IntPtr WinHandle,uint Msg);
and the function call is like this .....
..... some code.....<br />
uint[] Freqs = new uint[1001];
..... some code....<br />
if (!clsApiWrapper.G3BlockScan(radioHandle, <big>Freqs</big>, 1001, 256, 100000, pointer,Msg))<br />
MessageBox.Show("The block scanning failed to start", "WiNRADiO - Error Message", MessageBoxButtons.OK, MessageBoxIcon.Error); <br />
..... some code ....
But now when I run the app it doesn't change the contents of the array. so I believe I need to pass the reference of the array to the function. And if I change the code like this to pass the reference of the array
[DllImport("wrg303api.dll")] <br />
public static extern bool G3BlockScan(int hRadio, <big>ref uint [] Freqs</big>, int Count,int StopSquelchRaw,uint FeedbackTime,IntPtr WinHandle,uint Msg);<br />
<br />
..... some code.....<br />
uint[] Freqs = new uint[1001];
..... some code....<br />
if (!clsApiWrapper.G3BlockScan(radioHandle,<big>ref Freqs</big>, 1001, 256, 100000, pointer,Msg))<br />
MessageBox.Show("The block scanning failed to start", "WiNRADiO - Error Message", MessageBoxButtons.OK, MessageBoxIcon.Error);
Now when I access the Freqs array after the method call I encounter a strange behaviour.. The size of Freqs array is reduced from 1000 to 1.
I can't figure out what is going wrong.
Can any1 plz suggest what to do.

Hi
i have created a web services and when i try to run it it gives me this error""http://localhost:6058/WebSite1/Service.asmx"".so i don't know what problem might be cause even if i create a new one without coding still gives me the same error
|
|
|
|
|
that's not an error - that's the url of your service. Try sticking that in your browser.
Regards,
Rob Philpott.

That isn't an error. That is how you "run" the Web Service. If you still believe this is an error please give more information.

Hi
This is Dayakar,i have one problem
i have one project i depoyed that one
now i have exe of deployed project now i want to run this into some other system but that system does not contain dotnet framework
How to solve this problem

Install the appropriate version of the .NET framework on the other machine.

To basically reinforce what Josh said above, (and others have said below), you need to have the .net framework installed on every machine that is trying to run software programmed for that .net framework. On a much greater level, its like needing Windows to run software that was programmed for Windows.
Since it also seems like you're deploying for the first time(something I did about 3 months ago), if you start running into permissions errors, look up caspol.exe. The 2.0 framework SDK has a form that deals with permissions, but without that, you need to use caspol to give your application permission to run(in case it has problems).

You have to have the .NET framework to run .NET apps. If the computer has SP2 on it then the .NET framework should be installed.

dotnetfx.exe installs the .NET framework. There's no way around it Dayakar, if you want to run a .NET application, you need to have the .NET framework installed.

I created a simple COM Add-in Extensibility Project Type in C#.Net and integrated it with Visio 2003 managed custom toolbar.It was running fine but after few minutes i got some changes in my C#.Net code which i wrote for this COM Add-in and again i ran the code in Visio 2003 but this time it was not running,even i created some other COM Add-in extensibility project type sample but it was also not running.I don`t know that it is because of Visio 2003 or my code.
Please would you solve my this problem and please tell me about its reason.

If you made changes to the code and and the add-in fails to work, then it is more than likely going to be your add-in that's the problem. Are you able to post the source code that you changed?
