Hi,
I would like to create a small application to create/modify my app.config file, in which I store my database connection string.
1. I would like to know if it is possible to obtain a list of installed ODBC drivers on a PC.
2. Similarly, when I choose an ODBC driver, I would like to obtain a list of database appartaining to chosen ODBC driver.
Can anyone give me some clues/websites/articles, because all I found out is java and/or old C++.
Thanks + Regards:->

The app.config file is not supposed to be modified by your application for a reason. Why don't you take a look at the Enterprise Libraries Configuration Class instead?

I’m going to build an application that should be based on plugins that extend the core application with extra customer specific functions.
I like my plugins to have a common look, fell, and behaviour. I like tips on how to design my application to make it extendible. I like some tips on design patterns that could be useful.
I like to see my core-application as a framework for further development of plug-ins. I’ve read some articles on reflection and I get the point of it but I don’t really yet have the right thinking of how to apply common design patterns.
My other question is how I can get the look and fell of my plug-in dialogs like Visual Studios dockable windows. Is there any support for that in the .NET framework?
All tips on how I should start design my application and make it look good are welcomed!

Hi,
you could search for plugin[^] here on CodeProject to get a starting point.
There is no inbuilt support for dockings. Either have a look at this[^] or if you can afford to spend some money on it then here[^].

Thanks for your tips.

Hello, in runtime I create compoments (labels, checkboxs) later I want to clear those, but method that i`m using remove only half of them. Here is that method:
foreach (Control ctrl in Controls)
{
if (ctrl is Label)
{
Controls.Remove(ctrl);
}
}
|
|
|
|
|
You are not allowed to remove elements of a list within a foreach on it. You should do it this way:
for (int i = Controls.Count - 1; i >= 0; i--) {
if (Controls[i] is Label)
Controls.Remove(Controls[i]);
}
|

now it`s working, thank you very much.

I'm a newbie so excuse the simplicity of my question. I have to create a class which contains a total value sold in dollars and a total commission earned field that are intialized to 0 and a commissions rate field required by the class constructor. This is what I have:
public class AutoSalesperson
{
private double TotalValueNum = 0;
private double CommissionEarnedNum = 0;
private double CommissionRateNum;
I'm confused about the constructor especially
Thank you and have a good day

augie0216 wrote: a commissions rate field required by the class constructor
Do you mean that the class constructor takes this in as a parameter?
If so, try something like this:
public class AutoSalesperson
{
private double totalValueNum = 0;
private double commissionEarnedNum = 0;
private double commissionRateNum;
public AutoSalesperson(double commissionRateNum)
{
this.commissionRateNum = commissionRateNum;
}
}
Note: It is generally good practice to use camelCaseVariableNames (first char is lower case) for private fields of a class, local variables, and parameters.
Does this help?

I using theis code to disover new registre
**********************************************************************************8
if(OurKey !=null)
{
//find all the subkeys
daemonKey = OurKey.GetSubKeyNames();
//how many found?
numElements = daemonKey.Length.ToString();
count=Convert.ToInt32(numElements);
for(int i=0;i<=count-1; ++i)
{
newDKey=newDKey+daemonKey[i];
//label1.Text=newDKey; //LABEL 1
//reopen the registry with new path
RegistryKey OurKey1 = Registry.LocalMachine;
OurKey1=OurKey1.OpenSubKey(newDKey,true);
string status =(string)OurKey1.GetValue("Alive");/////line A
label1.Text = status; //Line B
}
***********************************************************************************************
The new path is read correct with (label1.Text=newDKey)
I am trying to read a DWORD value define by the DWORD key "Alive"
If I compile the program, no errors are reported but still cannot read the DWORD value into the label1.
Any help is greatly appreciated

I started developing a web part but am having some security issues with it. I am trying to do some really simple stuff as shown below.
<br />
SPWeb mySite = SPControl.GetContextWeb(Context);<br />
output.WriteLine(SPEncode.HtmlEncode(mySite.Users.Count.ToString()));
It is the SPWeb line that is giving me the security error which is:
Request for the permission of type Microsoft.SharePoint.Security.SharePointPermission, Microsoft.SharePoint.Security, Version=11.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c failed.
I started by making the webpart safe in the wss_minimaltrust.config file by using the Public key. That didn't work so I upgraded the trust level to Medium in the web.config file just to see what would happen. it still broke so I upgraded the trust level to Full. It still broke!
This code is used by many others all over the web but I haven't seen them having any issues. Full trust should allow everything so why am I still getting a security error?
Oh, and I did iisreset between each security change just to be sure it took hold.
Thanks for any help!

Ok, so duh...
I was editing the web.config located in Program Files\Common Files\Microsoft Shared\web server extensions\60\CONFIG when the web.config that needs to be edited is in the web root under Inetpub.

Hi,
I was just wondering if anybody else has same problem -> I can't seem to get this to work on other than UI thread. So this works if you call it directly on form
[DllImport("winmm.dll")]
private static extern long mciSendString(string strCommand,
string strReturn, int iReturnLength, IntPtr hwndCallback);
private void OnSomeButtonClick()
{
PlaySound(new object[] {"c:/sound.mp3", this.Handle});
}
private void PlaySound(object soundToPlay)
{
string soundToPlay = ((object[])data)[0];
Handle handle = ((object[])data)[1];
string sCommand = "open \"" + soundToPlay + "\" type mpegvideo alias MediaFile";
mciSendString(sCommand, null, 0, IntPtr.Zero);
sCommand = "play MediaFile wait";
mciSendString(sCommand, null, 0, handle);
string sCommand = "close MediaFile";
mciSendString(sCommand, null, 0, IntPtr.Zero);
}
But if you say:
private void OnSomeButtonClick()
{
ThreadPool.QueueUserWorkItem(new WaitCallback(PlaySound), new object[] {"c:/sound.mp3", this.Handle});
}
It won't play sound... anyone?
Tnx in advance

Hi!
I am trying to develop the messenger-like program and i need to make possible for clients to make the audio conversation to each other! Do i need to use RTSP or what? How is this option implemented in other popular messengers(MSN Messenger)!? Any help would be very very appreciated!
|
|
|
|

RTSP = TcpClient for control, UdpClient for communication is ql idea.
However you'll need a way to record wave and play it on other side... these two articles should help you do that pretty easily:
http://www.codeproject.com/cs/media/cswavrec.asp
http://www.eggheadcafe.com/articles/20050611.asp
Enjoy
|
|

|

But if i use TcpClient for control, doesn`t it mean i must use TCP for data transmition as well!?
And about recording and playback sounds, couldn`t that do with DirectX9 classes?
Thankx!
|
|
|
|
|
For TcpClient -> of course not. You can use TcpClient for recieving control commands ("START_SESSION", "END_SESSION"), and use UdpClient for data transport (it's faster)...
You can do recording with DX9.. but then all of your clients need to have DirectX 9 installed.

How can i implement RTP in c#!? I couldn`t find anybody to have done that! Why not use RTP protocol? I thought the RTP protocol was made for that kind of work!
