Thanks for the tip however it didn't work. The issue is definitly the compression type used to create the tiff image. I was able to resolve the issue using the original program that created the tiff to safe it with a different compression and then convert to Tiff.

Thanks

how can I calculate the total hours and minutes between two DateTimes? I tried this code but it's getting it correctly..

<pre>TimeSpan time_difference = DateTime.Now - Convert.ToDateTime(gridComputers.GetRowCellValue(i, "start_time"));

double usage_hours = time_difference.TotalHours;
double usage_minutes = usage_hours - ((int)usage_hours * 60);
string total_usage = String.Format("{0}h {1}m", (int)usage_hours, (int)usage_minutes);</pre>

If it is getting it correctly, then I don't see you have a problem!

Actually I do, but never mind. Why are you playing with

double usage_minutes = usage_hours - ((int)usage_hours * 60);

Why not use

double usage_minutes = tume_difference.TotalMinutes;

See example here[^]

I don't believe that would give the results the OP is looking for. For instance with a TimeSpan representing 1.5 hours, TotalMinutes = 90. I believe what he wants is 1h 30m

Makes sense! So use:

double usage_minutes = (double) time_difference.TotalMinutes % 60;

Unfortunately, TimeSpan is sealed so you can't simply inherit and modify some aspects. If you don't like its color, you'll have to redo everything from scratch. Make sure to implement full skinning capabilities, compatible with XP, Vista and 7.

Your problem is in usage_minutes. You subtract 60h from h, which gives you a total minutes value of -59 * usage_hours. What you should be doing is something like time_difference.TotalMinutes % 60 (excluding freaky stuff like leap seconds, etc)

'TotalHours' is not the same to 'Hours';
'TotalMinutes' is not the same to 'Minutes';

//for example
private string DateDiff(DateTime DateTime1, DateTime DateTime2)
{string dateDiff = null;
TimeSpan ts1 = new TimeSpan (DateTime1.Ticks);
TimeSpan ts2 = new TimeSpan (DateTime2.Ticks);
TimeSpan ts = ts1.Subtract(ts2).Duration();
dateDiff = ts.Days.ToString()+"days"+ ts.Hours.ToString()+"hours"+ ts.Minutes.ToString()+"minutes"+ ts.Seconds.ToString()+"seconds";
return dateDiff;
}

Is there a way to registry factories when an assembly is loaded?

k66610-Sep-09 8:01

I would like to implement factory methods to transfer data between the gui controls and my dataobjects. The gui controls can be ASP.NET web controls or Windows controls and I have a utility library for each environment. The dataobjects can run in either environment and should know nothing about which it is in.

So what I would like to happen is that when the Web utility library is loaded the webgui<->do bridges are registered and when the Windows utility library is loaded the wingui<->do bridges are registered. That way the dataobjects can send/receive data from the gui without knowing which gui it is.

It seems like such a basic requirements for factories. Is there a way to do this?

Problem with Visio ExportAsFixedFormat

Hi,

I'm trying to use ExportAsFixedFormat with a Visio Document. I'm using Office 2007 and Visual studio 2008.

Here is my code:
ApplicationClass visioApplication = new ApplicationClass();
Document visioDocument = visioApplication.Documents.Open(@"C:\temp.vsd");
visioDocument.ExportAsFixedFormat(VisFixedFormatTypes.visFixedFormatPDF,
@"c:\visio.pdf", VisDocExIntent.visDocExIntentPrint,
VisPrintOutRange.visPrintAll, 0, 0, false, true, true, true, false, null);

I've been trying different values for the bools and enums, but with no
success. All I get is a COMException telling me "Invalid parameter".

Any suggestions?
Thanks in advance.

You can do this without using regex. A possible solution could be (just an example):

string str = "Product : tempuri";

// Get the product "value"
string strProduct = str.Substring(str.IndexOf(":") + 1);
