I had problem with listbox in c#:

the problem is i have to listboxes the items in listbox1 moves to listbox2
and next button is pressed it moves to the nextpage if the items in listbox2 are moved back to listbox1 and next button is pressed it should show error message. upto here the functionality is working fine

the problem is there is a link below to delete the items in listbox1
once i deselect the items in listbox2 and then delete the items in listbox1
and press the nextbutton the message is not fired instead it is navigating to the next page.
I used javascript for moving the selected items from listbox1 to listbox2 and for deleting the items in listbox1

i require solution to this problem

Please translate your request into English Wink | ;)

Sorry, no code, no clear information, no screenshot = no answer.
Are you trying to do something like MS Access table creation wizard?

There are available, predefined columns on the left listbox, and you select,add them to the one on the right in this wizard. There are also, next, back like buttons. What do you want?

Well congratulations. Do you mean that you want an asset inventory system? If so, you're probably going to have to end up paying for one.

Call to Methods

Hi Friends,

How can I handle the call to specific methods based on a string value without comapring the string value using any of the control statements .
The requirement is explained as follows:

I have 3 methods here.

1. CallMethod(String s)
2. ProcessAgencyDataTable()
3. ProcessAuthorityDataTable()

Now, I should be able to call the method ProcessAgencyDataTable() when (s="Agency") for CallMethod(String s) and
ProcessAuthorityDataTable() when (s="Authority") for CallMethod(String s).

I should achieve this without using any of the control statements (like if, if-else, switch etc).
The CallMethod() should be able to call the specific method based on the value of s parameter.
Note: There will be some similarity in the Method names that will be called.

        public void CallMethod(String s)<br />
        {<br />
            switch (s)<br />
            {<br />
                   case "Agency":<br />
	          ProcessAgencyDataTable();<br />
                       break;<br />
                   case "Authority":<br />
	         ProcessAuthorityDataTable();<br />
                       break;<br />
                   default:<br />
                       break;<br />
            }<br />
        }<br />
<br />
        private void ProcessAgencyDataTable()<br />
        {<br />
           // Implementation here<br />
        }<br />
<br />
        private void ProcessAuthorityDataTable()<br />
        {<br />
           // Implementation here<br />
        }

Thanks for some suggestions.

You can build the method name dynamically and use Reflection to call the method.

using System.Reflection;
...
string methodName = String.Format("Process{0}DataTable", s);
Type t = this.GetType();
BindingFlags flags = BindingFlags.NonPublic | BindingFlags.InvokeMethod | BindingFlags.Instance;
t.InvokeMember(methodName, flags , null, this, null);
...

I don't know what this is for, but it could be that this could be better designed - for example, having separate classes or object instances for operations on each type of table. Then you could say:

agencyDataSource.ProcessTable();
authorityDataSource.ProcessTable();

In either case, you can have a dictionary to store the methods or objects by name:

//the object way
Dictionary<string, MyDataSourceObject> tableObjs = new Dictionary<string, MyDataSourceObject>();
...
tableObjs["Agency"]=agencyDataSource;
tableObjs["Authority"]=authorityDataSource;
...
tableObjs["Agency"].ProcessTable();
tableObjs["Authority"].ProcessTable();

//the method way
delegate void EmptyDelegate();
Dictionary<string, EmptyDelegate> methods = new Dictionary<string, EmptyDelegate>();
...
methods["Agency"]=ProcessAgencyDataTable;
methods["Authority"]=ProcessAuthorityDataTable;
...
methods["Agency"]();
methods["Authority"]();

Or you could do it using Reflection like Brady mentioned but it's slower as far as perf.

Thanks Justin,

When looking for the performance, your suggestion would serve better.
I will have to make a trade-off which way best suits for my Application.

Anyway, Thank you once again for your valuable suggestion.

Try using ReportViewier to print and use

ReportDocument rptDoc = new ReportDocument();
rptDoc.Load(Server.MapPath("ReportName.rpt"));
rptDoc.SetDataSource(yourDataSet);
CrystalReportViewer1.ReportSource = rptDoc;

the ReportViewer has a print button option, set it to true

CrystalReportViewer1.ShowPrintButton = true;

This usually selects all the printers added on that machine

i hope this helps

There is a property, PrinterName or some such, that you can set the printer name to.

Get Application directory from console program

I am writing a C# console program that needs to read a file from the same directory as the application. I can't use the current directory as that is not the same as the application directory.

Normally I would use Application.ExecutablePath, but console apps don't derive from Application.

Ideas?

The current directory is NOT the application directory.

If I open a command prompt, change to C:\Windows and run the application C:\MyProg.exe your example will not work. The file 1.log is in C:\, but the current directory is C:\Windows so I will get a file not found exception.
