If windows can't read it, then the codec in question is not supported by windows in general, and that's probably why iTextSharp can't read it either. That means you need to find a library that includes that codec, in order to work with those images.

I have read somewhere that it is possible to remove the tiff header as the file I am working with is basically a JPEG. Do you have any idea how to do that. The example code I saw was written in spanish. I can open the image using a file stream and read that into a byte array, but I don't know how to find the header information and strip it out.
Thanks for any info!

It's a jpeg inside a tiff ? You'd have to look for the file format online to work out what bytes you need to remove, in order to be left with the JPEG. It may be fixed number, or it could be variable and you'll need to parse it to work it out.

I believe it is a JPEG inside a TIF. It's a weird thing in an application I used to work on but didn't handle the Imaging software so I don't know anything about it. I am just hoping to find something that will do the trick.

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;

what is wrong with TimeSpan.Hours and TimeSpan.Minutes?

I don't like the colour.
That's my excuse, and I'm sticking with it.
Nothing to do with my forgetting about them, no siree!

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;
}

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?

Maybe have a look here[^]

I have a third party library which i have added to the skip verification list, using sn, on my computer.
I wanted to know whether the application (after deploying it on some other computer) will run?
Do i have to perform some other tasks after the deployment (setup)?

Yes it will work ,
SN protected the Application Exe bytes from begin modify.

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.

Thanks for your reply.
ExportAsFixedFormat function is working for word documents.
Problem is with Visio document.
Please provide the solution for the conversion of visio to pdf document.
|
|
|
|

Its not working in C#.net, but working in VB.net
So I created the dll and used in my application.
doc.ExportAsFixedFormat(Visio.VisFixedFormatTypes.visFixedFormatPDF, "C:\test.pdf", Visio.VisDocExIntent.visDocExIntentPrint, Visio.VisPrintOutRange.visPrintAll)
Thanks for the support
