Sorry, my mistake. The diagnosis still is right, the solution isn't as
this.Panel1.DrawToBitmap(bm, new Rectangle(0, 0, w,h));
is upscaling the existing panel content to the right size, however it cannot improve the quality of the image that your panel is holding.
You really need to do one of two things:
1. send print element commands to the printer directly (DrawString stuff);
2. paint whatever it is you need to a Panel of the right size (same dpi upscaling to get its size), then draw that to the printer.

Do not have a way to do this way?
Bitmap bm = new Bitmap(10, 10);
Graphics g = Graphics.FromImage(bm);
int dpix;
dpix = Convert.ToInt16(g.DpiX);
int dpiy;
dpiy = Convert.ToInt16(g.DpiY);
bm.Dispose();
g = e.Graphics;
int w;
w = Convert.ToInt16(this.Panel1.Width * g.DpiX / dpix);
int h;
h = Convert.ToInt16(this.Panel1.Height * g.DpiY / dpiy);
bm = new Bitmap(w, h);
this.Panel1.DrawToBitmap(bm, new Rectangle(0, 0, w,h));
e.Graphics.DrawImageUnscaled(bm, 0, 0);
bm.Dispose();

DrawToBitmap takes the available pixels and copies them to the destination, it does not know nor understand what it is your panel is showing, so it cannot improve how the text gets rendered. That is why I suggested you start with a bigger panel.

Graphics g = Graphics.FromImage(bm);
int dpix;
dpix = Convert.ToInt16(g.DpiX);
int dpiy;
dpiy = Convert.ToInt16(g.DpiY);
bm.Dispose();
g = e.Graphics;
int w;
w = Convert.ToInt16(this.Panel1.Width * g.DpiX / dpix);
int h;
h = Convert.ToInt16(this.Panel1.Height * g.DpiY / dpiy);
bm = new Bitmap(w, h);
this.Panel1.DrawToBitmap(bm, new Rectangle(0, 0, w, h));

Hi
I want to export Datagridview to excel. I have formatted my datagridview such that he negative values are shown as red, some values are bold and other formatting styles are applied. I want when I export it to Excel then it export with same formatted type.
Currently I Am using the below function to export. But unable to export with formatting.
private void exportAsExcel()
{
Microsoft.Office.Interop.Excel._Application app = new Microsoft.Office.Interop.Excel.Application();
// creating new WorkBook within Excel application
Microsoft.Office.Interop.Excel._Workbook workbook = app.Workbooks.Add(Type.Missing);
// creating new Excelsheet in workbook
Microsoft.Office.Interop.Excel._Worksheet worksheet = null;
// see the excel sheet behind the program
//Funny
app.Visible = true;
// get the reference of first sheet. By default its name is Sheet1.
// store its reference to worksheet
try
{
//Fixed:(Microsoft.Office.Interop.Excel.Worksheet)
worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Sheets["Sheet1"];
worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.ActiveSheet;
// changing the name of active sheet
worksheet.Name = "Sheet1";
// storing header part in Excel
for (int i = 1; i < dgvDetails.Columns.Count + 1; i++)
{
worksheet.Cells[1, i] = dgvDetails.Columns[i - 1].HeaderText;
}
worksheet.get_Range("A1", "AZ1").Font.Bold = true;
worksheet.get_Range("A1", "A" + (dgvDetails.RowCount + 2).ToString()).Font.Bold = true;
// storing Each row and column value to excel sheet
for (int i = 0; i < dgvDetails.Rows.Count; i++)
{
for (int j = 0; j < dgvDetails.Columns.Count; j++)
{
worksheet.Cells[i + 2, j + 1] = dgvDetails.Rows[i].Cells[j].Value.ToString();
}
}
}
catch (System.Exception ex)
{
}
finally
{
app.Quit();
workbook = null;
app = null;
}
}
Thanks in advance

How to open a document using word automation and read the bookmark values in it?This has to be done as a function...input of the function will be the full path of the file to be opened and a list of bookmark names.
|
|
|

Thank you but i am not able to goto the bookmark and bookmark names are not displayed(dont know whether i had inserted bookmarks correctly,please check).Following is the code:
Word._Application oWord;
Word._Document oDoc;
oWord = new Word.Application();
oWord.Visible = true;
object fileName = strFileName;
object readOnly = false; object isVisible = true;
object missing = System.Reflection.Missing.Value;
object oEndOfDoc = "\\endofdoc";
oDoc = oWord.Documents.Open(ref fileName, ref missing, ref readOnly, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref isVisible, ref missing, ref missing, ref missing, ref missing);
oDoc.Activate();
Word.Paragraph oPara1;
oPara1 = oDoc.Content.Paragraphs.Add(ref missing);
oPara1.Range.Text = "Heading 1";
oPara1.Range.Font.Bold = 1;
oPara1.Format.SpaceAfter = 24;
oPara1.Range.InsertParagraphAfter();
Word.Paragraph oPara2;
object oRng = oDoc.Bookmarks.get_Item(ref oEndOfDoc).Range;
oPara2 = oDoc.Content.Paragraphs.Add(ref oRng);
oPara2.Range.Text = "Heading 2";
oPara2.Format.SpaceAfter = 6;
oPara2.Range.InsertParagraphAfter();
Word.Paragraph oPara3;
oRng = oDoc.Bookmarks.get_Item(ref oEndOfDoc).Range;
oPara3 = oDoc.Content.Paragraphs.Add(ref oRng);
oPara3.Range.Text = "This is a sentence of normal text.Now here is a text";
oPara3.Range.Font.Bold = 0;
oPara3.Format.SpaceAfter = 24;
oPara3.Range.InsertParagraphAfter();
oDoc.Paragraphs[1].Range.InsertParagraphBefore();
object bm1 = oDoc.Paragraphs[1].Range;
Microsoft.Office.Interop.Word.Bookmark bookmark1 = oDoc.Bookmarks.Add("bookmark1", ref bm1);
bookmark1.Range.Text = "bm1";
oDoc.Paragraphs[2].Range.InsertParagraphBefore();
object bm2 = oDoc.Paragraphs[2].Range;
Microsoft.Office.Interop.Word.Bookmark bookmark2 = oDoc.Bookmarks.Add("bookmark2", ref bm2);
bookmark1.Range.Text = "bm2";
int nCount;
nCount = oDoc.Bookmarks.Count;
for (int i = 0; i < nCount; i++)
{
object objI = i;
MessageBox.Show(oDoc.Bookmarks.get_Item(ref objI).Name);
}

I'm doing a project in .net for little kids. So i need my UI to be eye catching. I'm hoping to use FLEX to do that.
first of all is it possible?
If so how can I do it?
Any help will be appreciated
Thanks.

Good god man, just use Windows Forms! Or maybe WPF (like Windows Forms, but all fancy smancy looking). But Flex (a Flash technology, right?) inside of Windows Forms... why oh why would you inflict that upon yourself?
|
|
|
|

Thanks for your reply,
But I've developed several components which are needed using FLEX. So now I have to integrate them with the win form.
Therefor I can't migrate to WPF now

If you want to do it in .Net, use WPF. It is quite good at flashy and unconventional UIs. If you want to use Flex, use Flex and make a SWF. Integrating them may be possible but it certainly won't be nice, you'd almost certainly be better off rewriting the custom controls you need. (Customising controls in WPF is quite easy, you can edit the template XAML.)

In case you haven't found out yourself, Adobe has some integration tutorials here.

hi,
What is a realTime application?
Is it one with multithreading?
If an application uses background worker process, can it be a realtime application?
Thanks
