Hi ! I am designing a simple calculator application and I am having trouble coding the backspace button. I store the data that the user had input in a string by the name of strInput with initial value strInput = "" .
I display the value that the user had clicked by coding :
lblDisplayPanel.Text+="value of button";
For example, lets take a look at my button 1
private void btn1_Click(object sender, EventArgs e)
{
lblDisplayPanel.Text += "1";
}
so when I click button 1 thrice, the display panel will show "111". However, I only know how to add values to the display panel label. I tried -= but it wont work .
The backspace button is supposed to remove the last value entered by the user but how do I do that ?

Try the following in your back space button click event
private void btnBS_Click(object sender, EventArgs e)
{
lblDisplayPanel.Text = lblDisplayPanel.Text.Remove(lblDisplayPanel.Text.Lemgth - 1);
}

Hi.
I'm building an application in winform environment that have a Tabcontrol in it.
That tabcontrol should have multiple lines in it.This can be done by setting the multiline property in the control.
But what i have trouble in is ordering the tabpaged in the control in a custom order.
for example , i want the first row to have 4 tabpages, second row 10 tabpages and so on....
can i accomplish that task without altering the tabpages width that causes
the tabpages to slide off to the next row?
thanks

1, Go to file menu > click Add > new project >now “Add New Project” Dialog appear.
2.Select “Other Project Types” and click “Setup and Deployment” projects,Choose “Setup Project”give name project name in name text box finally click OK.
3.New project appear in solution explorer,for example you give the name “MyEXE”..it will display with this name.
4.right click the MyEXE > go View > click “File System”
5.You can see the “File System on TargetMachine”under three folders
Application Folder
User’s Desktop
User’s Program Menu
6.Select Application Folder and right click Add>Project Output>select Primary output
7. select User’s Desktop richt click on the second window>click create new shortcut>select output file from Application folder>change the file name from primary output name to MyEXE
next >>
next >>
8.If you want to change the Manufactures name for exe,just right click the project go to properties
change the properties as per you requirement
9.Finally Build the new project After successfully Build the project myEXE(Setup) will be appear in Application Debug or Release folder(depend upon the properties settings)
EXE available @ this location
When you want to install the EXE on the client machine,you should be installed .NET Framework on that mc because,Applications and controls written for the .NET Framework version 2.0 require the .NET Framework Redistributable Package version 2.0 to be installed on the computer where the application or control runs.

Hi,
I am trying to consume a java web service in c#(windows forms client not asp.net client). The wsdl file opens in inernet explorer correctly (here also I have to give my usename and password i.e. an authenctication window opens and I enter my userame and password.)
But If I try to add a web reference to the service or try to create a proxy via wsdl tool I get the "The request failed with HTTP Status 401:Unauthorized" error. I tried by supplying username,password and the domain attributes with the wsdl command, but to no use. THe WSDL coomand I am using is as follows :
wsdl /out:myproxy.cs /username:nekuma2 /password:abc123 /domain:insidelive http://tkydte3pc40441:8080/fitsl/services/SimpleFixedIncomeTokyoService?wsdl
I have been breaking my head over this for a long time. Any help would be greatly appreciated.
Regards,
Neeraj

So what will be the correct forum for this?

"Java web service" means "Java". We have a whole freakin sub-site for java. If he doesn't want to go that far, he can try the web development form.

Seriously, did you even read the question? He is accessing a java webservice from a C# client. A perfectly valid C# question. Not even web related.

I think that will force NTLM (?) authentication, try without it.

Hi Leppie,
I tried without domain and it worked. Thanks for the suggestion. Though I still don't know what is NTLM authentication  ( guess i'll need to read it up). SOrry for the late reply. But I didn't have access to the code at home.
Thanks again.

I have an MDI form and multiple child forms... If i place any controls like label, buttons or textboxes on MDI form, These controls are visible even on the child form, how do i prevent this from happening.
|
|

|

Typically, controls aren't placed on the main form in a MDI application (except maybe a MenuStrip or StatusStrip).
