That is probably because the settings are stored in a ".config" XML file.
Check all of those in your debug directory, and you will probably find it.

Yes, I have found the config file in the debug folder and copied that also to C:\program files\AppName
But still ge tthe login failed error.
Not sure what is wrong because there is sql server and the login works as I can login using the application I have written when in the development environment.

As you know there is no installation mechanism with c# 2010 express, so as a test, I copied all the files (.dll, .exe, pdb...) from the release folder and placed them into c:\program files(86)\MyApp

So you are copying on the binaries from C# and are not attempting a copy of SQL Server correct?

If yes then I would expect something is wrong with your code to do the login. As an example (only an example) you catch an exception and instead of reporting the exception error you report a failed login.

Correct.
I am not copying the sql server because it is already installed with the database and login.
Pleas enote that the login works through the application when connecting to the database.

Thanks

Best practice is that you don't do this. SQL Server is only supported as a seperate install.

Once the server is installed and running seperately, your application installer can be told which SQL Server to use and what the login credentials should be to execute a SQL script to add your users and setup the database and its security.

Finding controls [modified]

Hello all,

I have two questions.
1) I have labels and textbox.
For ex;

lblName1.Text = txtName.Text;
lblName2.Text = txtName.Text;
lblName3.Text = txtName.Text;
lblName4.Text = txtName.Text;

Is there a way that i can do that in a loop something like:

for(i=0; i<4; i++)
{
lblName[i].Text = txtName.Text; // of course it does not accept [i] Smile | :)

}

2) How can I find a certain type of a contol in a webform and change the controls property.

Ex; I have 10 checkboxes. without coding one by one. Is there a way that I can assign its check selected to false more proper way ;

cb1.Checked = false;
cb2.Checked = false;
cb3.Checked = false;
.
.
cb10.Checked = false;

Thanks.

1) You can do it - sort of - with reflection, but it is one heck of a sledgehammer to crap a simple nut. What you end up with will be longer than the code to do it directly, and a lot harder to read and understand.
If you really want to access a number of controls in a loop, can I suggest the simpler, elegant way of having a class level list of labels?

List<Label>myLabels = new List<Label>();
...
myLabels.Add(lblName1);
myLabels.Add(lblName2);
myLabels.Add(lblName3);
myLabels.Add(lblName4);
...
foreach (Label lab in myLabels)
   {
   lab.Text = txtName.Text;
   }

2) Not sure what you mean here: are you trying to do the same as in (1) but for CheckBox? If so, then the same answer applies. If not, then what are you trying to do?

Well actually I mislead you on the first one it was like;
lblName1.Text = txtName.Text;
lblName2.Text = txtName.Text;
lblSurname1.Text = txtSurname.Text;
lblSurname2.Text = txtSurname.Text;

so seems like it is better for me to code it directly.

for the second one; after evaluating your answer, it seems like the solution for the second is the same with Q 1 Smile | :)

Anyway, even though you've apparently changed what you need to do, what you originaly asked for *is* possible, relatively easily done, and only moderately dangerous. Laugh | :laugh:

for (int i = 0; i < 4; i++)
{
    (FindControl("lblName" + i.ToString()) as Label).Text = txtName.Text;
}

Pretty sure, anyway.

Actually yeah that is what I tried to mean. That should do it thanks anyway though Smile | :)

but why is it dangerous?
I am guessing ;
During looping, when cant find a matching label name, it will throw an exception?

Re: Finding controls

GenJerDan11-Mar-11 14:44

GenJerDan

11-Mar-11 14:44

Yep. There had better be controls to match the loop variable number, or ka-boom!

Also: if, for whatever reason, you ever need the controlks to be set in a certain order...don't count on it. The compiler will do the loop in whichever order it feels is best.

Not tested, however I expect this should suffice:

for (int i = 0; i < 4; i++) FindControl("lblName" + i).Text = txtName.Text;

as each Control has a Text property, so no need to cast; and ToString() is implicit when appending to a string.

It won't compile.
'System.Web.UI.Control' does not contain a definition for 'Text' and no extension method 'Text' accepting a first argument of type 'System.Web.UI.Control' could be found (are you missing a using directive or an assembly reference?)

Or is there a switch somewhere to "relax" this?

Sorry, that was wrong. While true for WinForms, it ain't true for System.Web.UI so the cast is required!

Regarding 2), I would think you could put something like this in the code behind:

foreach ( Control c in this.Controls )
{
    if ( c is CheckBox )
    {
	( ( CheckBox )c ).Checked = false;
    }
}

No no.

1. For Each is VB, not C#

2. Form.Controls holds all top-level Controls of the Form, no matter what type they are; if one of them isn't a TextBox, foreach will fail to cast it and throw an exception, it does not enumerate just the derived type one is interested in!

hi All, I am having trouble doing some string manipulation. I get a string with coma delimited. I want remove the first portion of the string.

for example,strMessage = " I, Have, a, string, that, describe, something"
what I want to do is that remove the first coma delimited part of the variable strMessage so it look like this

"Have, a, string, that, describe, something" how do I do this. Any help appreciated.
then I insert the string in my datagridview.

datagridview.Rows.Insert(0,strMessage.Split(','))

I want to keep this style of inserting into dataGridView just want to remove the first portion of the string which is "I".

thanks

string.Split() is the method you want; it has a few overloads, so I refer to its documentation.

BTW: you won't solve problems any faster by putting as much as possible into a single statement. Split things up, and look at the intermediate values while debugging.

this is quite simple for the case you stated. That is just the first comma.

Use IndexOf. Something like:

str.Substring(str.IndexOf(",") + 1).TrimStart();//the TrimStart eliminates the white space after the "I,"

All the best,

Dan
