What database server are you planning on using? There are many of them (MySql, SqlServer, Oracle etc.).
If you are going to use SqlServer or Oracle, there are many articles on CP that can help.
If you are going to use MySql there is plenty of documentation on the MySql website that deals with .Net

Any of the major databases will suffice for the general query you posed. There is arguably more information on MS SQL Server than other DB. Just about every Database vendor now has a free version available for download and testing purposes.
I have currently queued up on my to read list “ADO.NET 2.0 Step by Step” by Rebecca M. Riordan, published by Microsoft Press. Glancing at it, it of coarse focuses on SQL Server but it does seem to talk about accessing and dealing with other db providers.
Hope that helps.

Hello
Is it necassary to know network programing?
GOOD LUCK

No, you just need to know ADO.Net. If you've ever connected to a Microsoft Access database it's pretty much the same thing. Try this article for some example code. It uses a MS SQL database and an Access database.

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
