Restart first starts a new instance of the application and then exits the existing instance.
If it would exit first, no one would be left to start the new instance.
|

Thanks Daniel,
But it doesn't always give the similar result. Some time it terminates properly but someting the instance still exist.
Most of the time if you are already in restarted application and you restart it again then it occurs more frequently.

I have encountered a typical problem while splitting a large file(.doc) in C# and then sending them via email. After splitting the files when I try to send them in email as attachment always the first part is not received at the destination ie if a file is split into 5 parts(part0,part1...part4) then the part0 is never received but is successfully sent.
I have even tried this with the file splitter program available in codeproject.
Any help would be appreciated?
|
|
|
|
|
One more update on this is when I use normal C program to split the files, all of them are received at the destination.

How do you expect people to help you if they can't see what you are doing? Showing the relevant code would go a long way here.

Also, this is happening only for .doc files.

hello,
im trying to write in process memory(of a game)at a specified address, but its not working, neither any error nor working, im new to API.
here is the code im using to write a int(4 bytes) value at 0xB7CE50.
IntPtr m_hProcess = IntPtr.Zero;
m_hProcess = APIDecalaration.OpenProcess(APIDecalaration.PROCESS_ALL_ACCESS, 1, ((UInt32)MYProcesses[0].Id));
APIDecalaration.WriteProcessMemory(m_hProcess, (IntPtr)0xB7CE50, 1000, 4, 0);
int isClosed = APIDecalaration.CloseHandle(m_hProcess);
if (isClosed == 0)
throw (new Exception("CloseHandle failed"));
APIDecalaration class :
public const int PROCESS_ALL_ACCESS = 0x1F0FFF;
[DllImport("kernel32", ExactSpelling = true, CharSet = CharSet.Ansi, SetLastError = true)]
public static extern IntPtr OpenProcess(UInt32 dwDesiredAccess, int bInheritHandle, UInt32 dwProcessId);

[DllImport("kernel32", ExactSpelling = true, CharSet = CharSet.Ansi, SetLastError = true)]
public static extern int CloseHandle(IntPtr hObject);
where i did mistake ???

I have a C# Form textBox that I would like to display a global counter that keeps track of different events. I would like to lock down the textBox so no input can be entered. Does anyone have an example of how to do this or a example of a better way of displaying this counter.
|
|
|
|
|
Hi
can can, You create a global property for the counter. and create a custom event for every evetn fiare in the any of the ur form trigger ur custom event and update the textbox by the ur counter value.
Basically u create a text box property readonly=true.
|
|
|
|

A TextBox has a ReadOnly property which you have to set to false. You could use a Label, but a TextBox is better because it still allows the user to copy-paste the contents.

Vikram.

Here is my coding that will show the ascii char in richtextbox.
string hex = "040";
string hex1 = "025";
string hex2 = "023";
string hex3 = "025";
int code = Convert.ToInt32(hex,16);
int code1 = Convert.ToInt32(hex1,16);
int code2 = Convert.ToInt32(hex2,16);
int code3 = Convert.ToInt32(hex3, 16);
richTextBox1.Text = Encoding.Default.GetString(new byte[] {(byte)code,(byte)code1,(byte)code2,(byte)code3});
Now i need arrange all the ascii char in correct position.I hd tried in many ways,but still got errors.pls help me.
Thank you.

well I need to display the customerID, firstName, and lastName from a table called customers into a listbox. The idea is that I want the user to view what customers are in the database and then pick one to update or delete. Then it will take you to a diffrent form where you can update or delete the customer.
|

|

sounds fun, what have you tried ?
Can't you just set the datasource of the listbox, or do you need to add columns in code ?

I don't think I need to add columns in code. I just need a listbox to display an ID number, first name and last name from a table in my database. We have connection to the database. I just need to know how to code the listbox to show these columns of my table.

Does it have a datasource property ?

I do not have a datasource. All I know is that I have a connection to the database and i know the select statement i need to put into the code.
|
|
|
|

Then when you call the SQL, you'll have a dataset. Which is a datasource.
So is an array, as it happens.

I'm kind of confused. You have SQL, but you don't know how to use it to get info into C# ? Have you done any research ? Is it a SQL Server DB ? Do you know how to create a connection string ?

I think u need to add column the to display the data from the Database.
Set the listview property to details. Then add columns
lyk:- listview.Columns.Add("Heading", width, allignment)
same for another column you want to add.
then create a datatable from database with the data u want, in ur case ID, FName, LName.
Loop thru the rows to show the data.
foreach(DataRow dr in dt.rows)//here dt is for datatable
{
listview.Subitems.Add(dr["ID"].tostring());
//same for Fname,
//& so on.....
}
The code here here is not syntactically correct.
Hope this will help you.

hello, id like to run console program from C# gui and catch its output and i have a problem that text in console is bigger than standard console width. is there a way how to set console width in C# for that process ?
maybe there is option in process.StartInfo how to use console with bigger width than standard 80 chars?
|
|
|
|
|
Hi,
I don't know you can do that programmatically, but maybe this helps: you can set it
manually by right-clicking the console window title, change window size and buffer size,
then save choosing "save for all windows with same title".
