IMO you are violating a lot of OOP concepts here.

Isn't it the other way?

Hi Guys,

I have a requirement in which i have to create folders and few excel files based on the no of launches and users during runtime.

when i click "download" button, i will have info of no of launches and no of users , so based on no of launches it should create those many folders and based on no of users in each launch, those many excel files in each folder should be created.

launches 5. then 5 folders to be created with the name of each folder is the launch name

if in launch 1, users 6 => in Launch1 folder, 6 excel files with the file name as the user name to be created. ( i mean these excel files are not default files but i have a template for this, that template with the user name should be created for this.)

if in launch 2, users 19, in Launch2 folder, 19 excel files with the file name as the user name to be created.

all this should happen at runtime...

please help me doing this

thanks

ramm

for creating Folders:
//if you want to create multiple folders then use for loop.
System.IO.Directory.CreateDirectory(@"D:\\your folder name");

for creating Excel file:

Microsoft.Office.Interop.Excel.Application m_objExcel;
Microsoft.Office.Interop.Excel.Workbooks m_objBooks;
Microsoft.Office.Interop.Excel._Workbook m_objBook;
Microsoft.Office.Interop.Excel.Sheets m_objSheets;
Microsoft.Office.Interop.Excel._Worksheet m_objSheet;
Microsoft.Office.Interop.Excel._Worksheet m_objSheetIntro;
Microsoft.Office.Interop.Excel.Range m_objRange;
object m_objOpt = System.Reflection.Missing.Value;
m_objExcel = new Microsoft.Office.Interop.Excel.Application();
m_objBooks = (Microsoft.Office.Interop.Excel.Workbooks)m_objExcel.Workbooks;

//Opening the Excel Sheets.
m_objBook = (Microsoft.Office.Interop.Excel._Workbook)(m_objBooks.Add(m_objOpt));
m_objSheets = (Microsoft.Office.Interop.Excel.Sheets)m_objBook.Worksheets;
m_objSheet = (Microsoft.Office.Interop.Excel._Worksheet)(m_objSheets.get_Item(1));
//Store excel in folder
m_objBook.SaveAs(@your path name here + "\\your file name here.xls", m_objOpt, m_objOpt,
m_objOpt, m_objOpt, m_objOpt, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange,
m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt);

Hi,

Right Click on Table and go to the Properties.
In properties window, select permissions and it asks for users .
U can enter the user list for the permission grant.

Hope this works out.

Thanks
Ramm

Wrong post... Any how, you can restrict access rights..
Database Name\Security\Logins
In logins you can search for that option...

drawing circles.

Hello All,
I have to draw concentric circles in such a manner that even if the form is resized the circles are displayed in the center of the form. I tried using DrawEllipse but I don't get the desired effect.
Can someone help.

You need to google first, if you have "It's urgent please" mentioned in your question.

Have you hardcoded the parameters in the DrawEllipse method?

Following code works fine:

gx.Clear(this.BackColor);
gx = this.CreateGraphics();
gx.DrawEllipse(Pens.Red, (this.Width / 2 - 10), (this.Height / 2 - 10), 20, 20);

I don't hardcode the values. I get the center of the form and then try to draw the concentric circles

So where is the problem then? Can you show some code and rephrase the problem?

_AnsHUMAN_ 28-Jun-09 20:52

Of course! Based on the size of the form I have to draw concentric circles ( A user can resize the form). So the center of the circles should remain at the center of the form(assuming square shaped form) always. Also the circles should shrink/grow as the user resizes the form. I hope it's clearer now.
In essence I have to create circles dynamically so that the center for two or more circles remain as the center of the form and the radius for each can be calculated in terms of a ratio.

The code I had posted does the same. What did you tried? Some code would be of help.

Your code only draws one circle at the center of the dialog. What if I want to draw two circles of different radius at the same center.

Use the method two times. Was it this tough?

_AnsHUMAN_ 28-Jun-09 22:22

28-Jun-09 22:22

You didn't read the documentation of DrawEllipse probably.
DrawEllipse - Draws an ellipse defined by a bounding rectangle specified by a pair of coordinates, a height, and a width. So we need to draw the bounding rectangle at the same center coordinates. Right?
When I use your code it draws an ellipse starting at the coordinates(left top corner) you provide and with the width and height, and so the circles are not concentric.

Anyways I have resolved the problem now.
Thanks for your time and effort in helping me.

Somehow, these look concentric to me.

gx.Clear(this.BackColor);
     gx = this.CreateGraphics();
     gx.DrawEllipse(Pens.Red, (this.Width / 2 - 25), (this.Height / 2 - 25), 50, 50);
     gx.DrawEllipse(Pens.Red, (this.Width / 2 - 50), (this.Height / 2 - 50), 100, 100);
     gx.DrawEllipse(Pens.Red, (this.Width / 2 - 75), (this.Height / 2 - 75), 150, 150);
     gx.DrawEllipse(Pens.Red, (this.Width / 2 - 100), (this.Height / 2 - 100), 200, 200);

aren't you hardcoding the values for the rectangle. you are fixing the centers by subtracting some values based on the radius. isn't it? your circles won't get drawn with the same center when you increase or decrease forms size.

Only thing I have fixed is the radius of the circles, and that is because this is just some sample code.

You need to handle the Resize event for the form as well and only then, no matter how you resize the form, the circles will be drawn with form's center as their center.
