Hello,
I have never used the printing functionality in C#.
I am having a data grid which is having 3 colums. I want to print one column out of three and some more custom data with this column. I want to print the data in tabular form with some header lines like "Name", "Date" etc.
How do i print in C#.
Thank a lot in advance.

Let's have a look at the datagrid print code i am writing......
private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
int iHorzResolution = e.PageSettings.PrinterResolution.X;
int iVertResolution = e.PageSettings.PrinterResolution.Y;
int iPaperWidth = e.PageSettings.PaperSize.Width;
int iPaperHeight = e.PageSettings.PaperSize.Height;
int iWidthPixel = iPaperWidth * iHorzResolution/100;
int iHeightPixel = iPaperHeight * iVertResolution/100;
PaintEventArgs myPaintArgs = new PaintEventArgs(e.Graphics, new Rectangle(new Point(0, 0), new Size(iWidthPixel, iHeightPixel)));
this.InvokePaint(datgrdSerialNumber, myPaintArgs);
}
private void btnPrint_Click(object sender, EventArgs e)
{
printDocument1.Print();
}
Now if i fire the print command, i am not getting the size of of grid accroding to my page(A4). It just prints the grid in left corner. Where am i going wrong???
Thanks.

Hellow, ho do i can to prevent removing row from DataTable. I.e. when row are being removed
by user, i need to validate this action and only after this remove this row or cancel this if neccessary.
I can't use RowDeleteing event because this one can't prevent row deletion if needed, such as only way to do this (as i know) is throw an exception and catch one by myself. But in my code i can't controle exception what throw my DataTable.
Thank.

Could someone please help me with this loop I'm working on.
The goal is to end up with a list of rar-files to be deleted after unpacking.
I have a list of the first rar-files in the span and I want to get the rest.
For the new-style rar-files, I figured I remove the ".rar" and ".part" from the filename
and just add one number higher, but that doesn't work since there are zeros to account for.
For the old-style rar-files I'm even more lost since there are booth zeros and letters added.
I know the letters are added one higher but I can't figure out a good way to do it.
This is what I've got now:
"rarsToDelete" contains the first rar-files in span
"rarSpanList" should contain the rest of the files in the end
private void DeleteRarFiles()<br />
{<br />
if(rarsToDelete != null)<br />
{<br />
ArrayList rarSpanList = new ArrayList();<br />
foreach (string s in rarsToDelete)<br />
{<br />
string fileNoExt = s.ToLower().Substring(0, s.LastIndexOf(".")-1);<br />
if(fileNoExt.EndsWith(".part1"))<br />
{<br />
string fileNoExtNoPart = fileNoExt.Substring(0, s.LastIndexOf(".") - 1);<br />
int i=2;<br />
string testFile = fileNoExtNoPart + "part" + i;<br />
while (File.Exists(fileNoExtNoPart + "part" + i))<br />
{<br />
rarSpanList.Add(testFile);<br />
i++;<br />
}<br />
<br />
}<br />
else if(File.Exists(fileNoExt+".r00"))<br />
{<br />
<br />
}<br />
}<br />
}<br />
}
Thanks

Look at the System.IO.Path class, it will save you alot of the grieve you are attempting now 
xacc.ide
The rule of three: "The first time you notice something that might repeat, don't generalize it. The second time the situation occurs, develop in a similar fashion -- possibly even copy/paste -- but don't generalize yet. On the third time, look to generalize the approach."

obj.dog() is private, you cannot call it. the compiler throw an error.
if you make it public, then you can call it.
private : can only be called inside that class.
public : can also be called outside that class.

If u r writing this code in C# then u must have to specify the return type for the function
and this code can't run
bcz u can't access the private variables
even the intellisense will not show u the private members

Trustapple wrote: can anybody help me to understand private ,public functions and keywords and how they affect inheritance.....i tried a couple of codes whre i made base class method private and tried to call them and its calling just like a public method....so i think i am missing something.
for example
class animal
{
private dog()
{
}
}
class bird
{
private sparrow()
}
}
class mainclass()
{
animal obj = new animal();
obj.dog();
}
this works fine so what is the use in making the method private????
any kind of help will be appreciated
OK - 1st - get a book. Read the first few chapters, type in a few examples, then, when you get stuck post here.
Your code generates at least 10 errors on compilation. Did you try it out?
class animal
{
private void dog()
{
}
}As somebody else said - methods need a return type.
class bird
{
private sparrow()
}
}No return type, no closing brace, not even used in Main - let's forget about this for now.
class mainclass()
{
animal obj = new animal();
obj.dog();
}I haven't a clue what this is about...class mainclass()? I assume you meant
static void Main(string[] args)
{
animal obj = new animal();
obj.dog();
}
Which, if you attempt to compile gives
Error 1 'TestApp.Program.animal.dog()' is inaccessible due to
its protection level
So, private does what it says it does - it is private. NObody can see it, except from within the Animal class.

Trustapple, I'll re-itterate my advice from umpteen times in the last week. You will learn ALL of this stuff much much better if you go and find yourself a biginner book on programming. There is no shame in doing so - we all had to start somewhere.

Try
String[] arrayOfHtmlLines = System.IO.File.ReadAllLines("myHtmlFile.html");
This will give you an array of lines.

I will happily help you - it is what we do here. You post the code you have tried and I or somebody else will tell you what is wrong with it. We will not write a whole program for you unless you pay us.

Do you mean the content of <body></body> tags ? Then you can
1 - Open HTML page and store the text in a variable
2 - Find index of <body> and </body> tags inside it.
3 - Use substring to get the values in between these tags
OR
4 - Use a regular expression to find the text in between these tags

hi does anyone know how to export a ssrs report programmatically into rtf / word,/ xml /csv formats?

You asked this yesterday - what have you tried to do between now and then to get it to work? Post a code snippet - people here love going through code and if you've made an effort, then they will also make an effort to help.
I am not saying you haven't made an effort before I get shot down in flames, but this question is too general.

Hi guys.
I'm building a windows service that uses an ActiveX object.
When I try to instantiate the ActiveX I get this error.
Could not instantiate ActiveX control 'XXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX' because the current thread is not in a single-threaded apartment.
I've changed the thread apartment style in the service, instantiated the ActiveX in a separate STA thread and still get the error.
Have any of you been in a similar situation ? if so, have you found a solution ?
Thanks in advance
Free your mind...
