hi all,
I ve a problem.I created a user control(Marquee control,logic:-drawing the string at system.Threading.Timer event),it is working fine.When I place the control in one of the form(form is accessing a web service,will take few seconds to get the data),control is not running smoothly.it is hanging for a while (web serice cause the delay).I created a thread & put the WS,Now the form(GUI) is hanging for a while,when it refresh the marquee text is running like Fast forward for a while.It means the marquee is running at the back ground, but I can not see,how to make marquee visible(running smoothly)
Thanks in advance,
ebin

Hi,
I often see [STAThread] above the main method of other people's classes, but I honestly have no idea what it does  someone willing to enlighten me? (I know its static thread, but what does it DO?)

Hello,
It marks the main entry point for the application.
Your programm will start at this point, in the main thread.
All the best,
Martin

Isn't that what the Main method is for?

You are write it's an Attribute for the Main method.
Which marks it as "Single-Threaded apartment" like 'Michael Sync'[^] said befor!

It's not for marking the entry point but rather specifying the threading model. See here[^] for some details.

Sir,
Actually I have written following code to export a crystal report in excel. It works in my local PC very well but it's not working in Web server.Ms-Excel is available in web server.Second thing is that if I convert it in .pdf then it's working successfully.Just I face problem in excel only.So I can't rectify the problem?? I think some driver or patches are used in this code which are not available in web server.Can u send me the list of pre-required components??
Sir pls reply immediatly.It's very imp.
My code is
ReportDocument oRD = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
DiskFileDestinationOptions oExDo = new CrystalDecisions.Shared.DiskFileDestinationOptions();
oRD.Load(Request.ServerVariables["APPL_PHYSICAL_PATH"].ToString() + "Weekly_Reports\\crpCommonFieldCom.rpt");
ReportDefinition oDef = oRD.ReportDefinition;
// Sub Report1
foreach(ReportObject obj in oDef.ReportObjects)
{
if (obj is SubreportObject)
{
SubreportObject oSub1 = (SubreportObject)obj;
ReportDocument oRdSub1 = oSub1.OpenSubreport(oSub1.SubreportName);
if (oSub1.SubreportName == "crpM35.rpt")
{
oRdSub1.Database.Tables[0].SetDataSource(ds.Tables["M35"]);
}
if (oSub1.SubreportName == "crpM30.rpt")
{
oRdSub1.Database.Tables[0].SetDataSource(ds.Tables["M30"]);
}
if (oSub1.SubreportName == "crpM25.rpt")
{
oRdSub1.Database.Tables[0].SetDataSource(ds.Tables["M25"]);
}
}
}
ExportOptions oExO;
string strFile = Path.GetTempPath() + Session.SessionID.ToString() + ".xls";
oExDo.DiskFileName = strFile;
oExO = oRD.ExportOptions ;
oExO.ExportDestinationType = ExportDestinationType.DiskFile ;
oExO.ExportFormatType = ExportFormatType.Excel;
oExO.DestinationOptions = oExDo;
oRD.Export();
oRD.Close();
Response.ClearContent();
Response.ClearHeaders();
Response.ContentType = "application/vnd.ms-excel";
Response.WriteFile(strFile);
Response.Flush();
Response.Close();
//delete the exported file from disk
System.IO.File.Delete(strFile);

Check the checkedbox "Ignore HTML tags in this message (good for code snippets)" when pasting the code.

You posted a lot of empty messages!

You can, I'm sure!

You forgot to turn the HTML tags off.
'Ignore HTML tags in this message'
Or use the 'pre Tags
P.S.: You should delete the other posts!

Hello!
I'm trying to read some data in from Excel.
Now the spreadsheets that I'm accessing contain columns of data, and these columns may sometimes be blank, the main table might start a few columns in and so on.
A raggedy old spreadsheet!
In addition to this I don't know how many rows or columns there will be, so I need to be able to handle this.
All the examples I've seen in the searches I've made have hard-coded limits.
For example my table might look like this (can't quite format this right, but you'll get the idea):
DEPT.M LLD.OHMM MSFL.OHMM RHOB.G/CM3 NO SONIC IGLOO FISH#
1450 12.4303 2.279 2.3188
1450.25 12.4494 5.0599 2.3323
1450.5 14.7747 2.0675 2.2776
1450.75 14.768 1.2149 2.217 0.3974
1451 13.1767 0.4151
1451.25 16.8165 0.2921 0.3974
1451.5 29.4913 0.4151
1451.75 48.8114 0.2921
1452 44.7025
1452.25 28.3492
1452.5 19.2471 2.2749 2.1967 13.1371 0.3974
1452.75 13.4801 1.8502 2.232 13.3881 0.4151
1453 3.2926 2.3583 13.8325 0.2921
1453.25 3.6341 2.4099
1453.5 4.1754 2.356 102.0509 16.9615 10.3197
1453.75 16.9615 5.3556 2.3608 106.603 18.0078 10.7229
1454 18.0078 4.9902 2.3258 105.3982 17.1981 10.2939
1454.25 17.1981 4.6068 2.249 108.3167 16.2081 9.6294
1454.5 16.2081 3.389 2.2199
1454.75 15.7188 1.9904 2.1252
1455 18.0351 128.8776 1.7491
1455.25 28.9451 656.4312 1.4863
1455.5 43.2879 65.2774 1.6644
1455.75 31.8807 12.309 2.182
1456 18.3605 9.6465 2.3213
1456.25 19.039 7.1053 2.1123
1456.5 25.825 9.4629 1.6977
I have this kind of example below, but the limits are hard-coded. How can I get the correct limits so that I can read the whole sheet, regardless of it's size?
<br />
<br />
Excel.Worksheet worksheet = (Excel.Worksheet)sheets.get_Item(1);<br />
<br />
for (int i = 1; i <= 10; i++)<br />
{<br />
Excel.Range range = worksheet.get_Range("A"+i.ToString(), "J" + i.ToString());<br />
System.Array myvalues = (System.Array)range.Cells.Value2;<br />
string[] strArray = ConvertToStringArray(myvalues);<br />
... etc<br />
}<br />
<br />
But what I really want is (pseudo-code in CAPS):
<br />
for (int i = 1; i <= worksheet.NUMBER_OF_ROWS; i++)<br />
{<br />
Excel.Range range = worksheet.get_Range(THE_WHOLE_ROW[i]);<br />
System.Array myvalues = (System.Array)range.Cells.Value2;<br />
string[] strArray = ConvertToStringArray(myvalues);<br />
.. etc <br />
}<br />
Or maybe there's a better way to get at all the data?
Thanks in advance for any help you can offer.

Hopefully this is still relevant to you . . .
to do worksheet.get_Range(THE_WHOLE_ROW[i])
we use this snippet:
int lastUsedColumn = worksheet.Cells.SpecialCells(XlCellType.xlCellTypeLastCell, Type.Missing).Column;
Range firstCell = (Range)worksheet.Cells[rowNumber, 1];
Range lastCell = (Range)worksheet.Cells[rowNumber, lastUsedColumn];
Range wholeRow = worksheet.get_Range(firstCell, lastCell);
