Hi All,

I have deployed my project and people are having trouble because the link for the InstallUrl is one that redirects you.
http://go.microsoft.com/fwlink/?LinkId=9832

Under the launch conditions in the Microsoft .NET Framework it has a red exclimation point on it. How do I fix this? I programmed in Visual Studio 2005. Should I Allow Later Versions?

To test a stored procedure ensure you have a known set of inputs. That includes the contents of the tables as well as the parameters. Run the stored procedure and ensure the output is as you expect. There isn't a lot more to it than that. The difficulty is ensuring a consistent input set so you are not tracking down false failures in the stored procedure when the test data is at fault.

ComboBox and BindingSource

Hello. I have a problem and I hope you can help me.
I have the two classes below.

public class MyObject
{
int _id;

public int Id
{
get { return _id; }
set { _id = value; }
}

string _name;

public string Name
{
get { return _name; }
set { _name = value; }
}
}

public class MyClass
{
MyObject _object;

public MyObject Object
{
get { return _object; }
set { _object = value; }
}
}

In my program I do that:

MyClass m = new MyClass();

private void Form1_Load(object sender, EventArgs e)
{
bindingSource1.DataSource = m;
}

and I create a comboBox and set his DataBinding to the "bindingSource1 - Object".
I populated the comboBox with Items.
My questions are: How can I populate the ComboBox with the Object, and when I select a Item from comboBox, that is a Name, he must give to me the Id for that Name.

Limit number of copies of application to 1

I have an application where the user(s) must only be able to open one copy of the application. I created a Mutex object that is created on startup to limit the number of possible copies on the computer that normally runs to software to just one, but it is possible at present for the customer to install this software on multiple machines. If someone opens a copy of this software on one machine while a user on another computer is running the software, that could create problems. Is there a way to check whether a process is running on another machine on the customer's network and, if so, to shut down the copy of the application the user tried to start up? Thanks.

This may seem like a difficult problem to solve, but what you need is a piece of server software that keeps track of the number of instances currently running. Then in your client software (the actual application being run), you need to have it first connect to the server software and find out how many instances are currently running. If greater than zero, display a message to the user, otherwise allow the program to continue.

Hope this helps.

Hi,
In visual 2005 I Created a new MDI project and by defualt it has a nice GUI with menus and toolbars. In addition, I have create a child form and can successfully load within the MDI parent form. Now, I would like to change the top menus i.e File,Edit,Help sorting order whenever a childform is opened that has it's own menu.

For instance by default:
File Edit View Help

When a childform is opened I want to display its menu like

File Edit GridView View Help

Thanks

Never done it myself but I think this should be possible using the MergeOrder and MergeType properties of MenuItem class or MergeAction and MergeIndex properties of ToolStripMenuItem class, respectively.

manipulating request headers for a service call

jhinze2-Apr-07 5:15

2-Apr-07 5:15

I'm calling another C# service from a http request handler and I need to add a persistant cookie to the service request.

I've tried from within the procedure that initiates the service call:

HttpCookie mycookie = new HttpCookie("myCookie");
httpContext hc = HttpContext.Current;

myCookie.Value = File.ReadAllText("c:\\temp\cookie.txt");
hc.Request.Cookies.Add(myCookie)

<call the="" service="">

What I get is the HttpContext is Null and I can't add anything to it. I'm obviously going about this the wrong way, can someone give me a shove in the right direction?

Thanks in advance!

The first one.

Seriously, your question is too broad and general to get a meaningful answer. You're more likely to get a meaningful answer if you post specific questions, e.g. "For a client/server architecture where both are .NET apps, should I use .NET remoting or WCF?"

wanting something to work doens't make it so Wink | ;)

you have to actually execute the command, and then read it with a reader, or alternatively fill a dataset with the results and read them from there.

Look up some ADO.NET tutorials.

What you are doing right now, and where it fails, is easily explained:

krajah1984 wrote:
string commandString = "SELECT password from table1";

SqlDataAdapter dataAdapter = new SqlDataAdapter(commandString, conn);

string strEnteredPassword = textBox1.Text;
if (strEnteredPassword == commandString)

you are checking if "ABCD" is equal to "SELECT password from table1".

Visual Studio can't evaluate this, can you?

public object moo<br />
        {<br />
__get { return moo; }<br />
__set { moo = value; }<br />

I told you what your mistake was. You can't just compare a command to the desired result. You have to execute the command, get the results, and then compare these.

Pleae follow this tutorial, it will help you a lot probably:

Just put the entire HTML file into a string, remove the carriage returns then run your reg expr.
