The usual procedure is to select text and set its properties.
Why "without selecting text"?

maybe I will have to do it like that then but if I select the text is there a way that as I change sizes it shows the text changing as well
|
|

|

Like this[^]?
Use "richTextBox1.SelectionFont.FontFamily" to keep the same font.

You will have to create a selection in the RichTextBox to change the font-size.
However, you can do that programmatically in a way that the visual state change the user will see is minimized. For example:
private void SetFontSize(int start, int end, float fontsize)
{
int currentselstart = richTextBox1.SelectionStart;
int currentsellength = richTextBox1.SelectionLength;
richTextBox1.SuspendLayout();
richTextBox1.Select(start, end);
richTextBox1.SelectionFont = new Font(richTextBox1.Font.FontFamily, fontsize);
richTextBox1.ResumeLayout();
richTextBox1.Select(currentselstart, currentsellength);
richTextBox1.Focus();
}

Hello there,
WORK:
I am working on a project, in which the output of some methods create a excel sheet.
PROBLEM:
When I run the project from IDE, the excel file is created properly and with all data from List<t>. But, when its run from the compiled EXE file, I am getting no output in the excel file.
Please help.

Wow. You're expecting a lot from us here. No code, only a description of the problem. I'm not sure you're going to get much more help than this I'm afraid.

Have you recompiled your project making sure that 'release' is selected in the configuration dropdown?
It could be that you have 'debug' selected and when you run from the IDE you are running in debug mode but never recompiling in release mode.

Hi GuyThiebaut,
I tried that too, but getting no success.

Here is the code:
public void WardList()
{
#region Load Values...
int count = 1;
List WWList = new List();
Engine E = new Engine();
SQLiteCommand CMD = new SQLiteCommand(E.SelectSQL("WARDS") + " ORDER BY [WARDNUMBER];", E.Conn);
SQLiteDataReader RDR = CMD.ExecuteReader();
while (RDR.Read())
{
WardWise WW = new WardWise();
WW.Serial = count;
WW.WardNumber = Convert.ToInt32(RDR["WARDNUMBER"]);
WW.WardCount = WardCount(WW.WardNumber);
WW.Name = RDR["NAME"].ToString();
WW.Manager = RDR["MANAGER"].ToString();
WW.TotalTax = WardExists(WW.WardNumber) ? WardWiseTax(WW.WardNumber) : 0;
WW.TotalPaid = WardExists(WW.WardNumber) ? WardWiseTax(WW.WardNumber, false) : 0;
WW.Balance = WW.TotalTax - WW.TotalPaid;
count++;
WWList.Add(WW);
}
#endregion
using (ExcelPackage EP = new ExcelPackage(Masters, Template))
{
double hook = 8;
ExcelWorksheet Sheet = EP.Workbook.Worksheets["AWW"];
foreach (WardWise WW in WWList)
{
Sheet.Cells["A" + hook].Value = WW.Serial;
Sheet.Cells["B" + hook].Value = WW.WardNumber + " [" + WW.WardCount + "]";
Sheet.Cells["C" + hook].Value = WW.Name;
Sheet.Cells["D" + hook].Value = WW.Manager;
Sheet.Cells["E" + hook].Value = WW.TotalTax;
Sheet.Cells["F" + hook].Value = WW.TotalPaid;
Sheet.Cells["G" + hook].Formula = ("E" + hook) + "-" + ("F" + hook);
hook++;
}

That is just a code dump, and gives no more clue that your original question. You need to explain where the problem occurs, since we have no idea how this code is supposed to work.

Start by looking at the input and output files: are you using absolute paths? Relative paths? Are they all looking at the same files?
What are the folders like - do they have suitable permissions, if they aren't the same?
Are the debug and release versions running on the same computer? Under the same user?
What happens if you execute the debug version directly in the same way you did with the release?
Do you get any error messages? Are you swallowing any exceptions?
You need to get information on exactly what is happening - we can't run your code in isolation!

Hi OriginalGriff,
The code for input and output files is
private static readonly string TemplatesFile =
Path.Combine(Directories.CurrentDirectory, "Reports", "ReportsTemplate.xlsx");
private static readonly string MastersFile =
Path.Combine(Directories.CurrentDirectory, "Reports", "Master.xlsx");
private static FileInfo Template = new FileInfo(TemplatesFile);
private static FileInfo Masters;
The folders have suitable permissions.
Yes, Debug and Release version are on the same computer, under same user.
When I run the EXE file I am not getting any output on both Debug and Release versions, but getting nice excel report when I run it from the IDE.
I am getting no errors. But, in the output window of the IDE, I am getting lots of First Chance Exceptions like this:
A first chance exception of type 'System.ObjectDisposedException' occurred in System.Data.SQLite.dll
Even though, I am getting a nice excel report. But not from EXE file.
Regards.

You are using relative paths - relative to the current directory, which will default to the folder the app is run from - so check that you are looking in the right folder when you run the code.
And I'd look in the debugger at where the exceptions are happening and why - it may be that they are relevant to your problem, and it works because the debugger is trapping the exception and letting you know it occurred. In the "undebugged" version, they may be stopping your code running. If you look on the VS Debug menu, you can tell it to break on all exceptions, caught or not.

I'd recommend that you debug it line by line and check if everything is happening as expected, is line 1 getting the values? how about line 2? 3? and so on. is every object instanced correctly? must of the times something really small is what is causing the problem.
When you execute the code inside visual studio, the application runs from the debug/release folder, are you executing it from the same location? or you copied the exe to a different folder? could it be is the paths you're using to read and write are not returning a valid path?

This isn't going to help since he states that the program works as intended when run under the IDE, which of course, is what he'd be doing in order to debug.

Hi Gonzoox,
Thanks for the reply. Yes, I had executed and executing the program from the same folder as it was created by the IDE. Moreover, debugging line by line, I am getting proper watch values on each variables.
Even though, I will debug it once more as you said.
Thanks.

As others have already said, more info would be needed in order to solve the problem. However, I understand the difficulty since the project works in IDE but not as an executable.
So what I suggest is that you add some kind of 'messaging' into the code. It could be writing a log file or something similar or simply just show message boxes. Add these messages to the code and run the exe. This should give you better understanding about the execution. Try to add relevant info into the messages such as working directory or the full paths of the file names etc.
With the messages you see more easily what happens and what code is reached and what is not.

Hi Mika,
As you said I designed a logfile stream writer and now I got my log file full of these two errors:
ERROR: Cannot access a disposed object.

And here is the code where I am getting those errors:

CUSTCMD.Parameters.AddWithValue("WARDNUMBER", WardNumber);
SQLiteDataReader CUSTRDR = CUSTCMD.ExecuteReader();
Calculate CT = new Calculate();
while (CUSTRDR.Read())
TT += CT.LedgerBalance(CUSTRDR["DEMAND"].ToString())[1];
CUSTCMD.Dispose();
CUSTRDR.Dispose();
CT.Dispose();
return TT;
}
catch (Exception ex) { LogEvent.WriteErrorLog(ex); return 0; }
}
private double WardWiseTax(Int32 WardNumber, bool TotalPaid)

}
CUSTCMD.Dispose();
CUSTRDR.Dispose();
CT.Dispose();
return (TotalPaid) ? TT : 0;
}
catch (Exception ex) { LogEvent.WriteErrorLog(ex); return 0; }
}
Please help...

As far as I can see the problem is that the connection is stored in another class, perhaps a static one. Based on this any method can dispose the connection and you would see this as a problem in the next call when the disposed connection is trying to be used. So probably the dispose happens elsewhere.
To correct this you would need to do a little bit of a re-design. I've touched this problem in Properly executing database operations[^]. Have a look at the initial version and differences in version 2. I think that clarifies the situation.
