Binding a toolstrip sub menu combo box

23-Sep-09 15:01

1) you can lighten text , so the text is clearer.
2) you can make two pictures (one is lighten, the other is darken)
when mouse over the places , just change the pictures.
3) of course, you can draw a picture, by different way.(Pixel Zoom, different background color.....)

Hello

I've a strange behaviour
If I add a ToolStripCombo in a toolstripmenu; I can bind that combo to a datatable and all is ok

BUT if I add a toolstripcombo in a second level (under a drop down button for example) the combo bided to the same datasource remain empty

What I'm doing wrong in such case ?

Thank for any help

why do you want to bind the datasource,
consider to use 'for loop' to add datas one by one.

Hello

I would answer :

Why using a loop as long as databinding should works ?

But if the answer is that DataBinding never works in such case , we can consider that as a "bug" and use a loop as a turn around Cry | :((

Your best bet is probably to look around to see if MS offer an SDK for SkyDrive. I've had a quick google around (by no means a thorough one) and can't find anything, but that doesn't mean something doesn't exist.

Slightly off topic, but it's probably not a good idea to post what appears to be a real email address to a public forum, unless of cause you like reading spam Wink | ;)

How to create a named pipe with data stream

Hi
I am looking for someone who can advise me and show an example of how to create a named pipe - one in and one out - with data stream.

To elaborate a little, I need to create a named pipe connection which will pass textual data from a desk top PC to an external device, which will be attached via USB cable. I need two named pipes - one to pass data down to the device and the other pipe to pass messages back to the PC from device.

Can anyone provide any help or example code for me, please?

Hi I have done in Win32dll (c++) project and i have used it in C#, using Dllimport[]

One function update the data stream in one thread(running program)
Another function receive the same data stream in another thread(another running program)

You can use
CreateFileMappingA - to create and update the data stream
OpenFileMapping - to read the data stream.

these function are available in winsock2.h

Using iTextSharp to Convert Tiff files to PDF

named pipe is always used in vc, c++ program.
if you want to use it in c# program.
consider to use win32 Api to create it.

//sever
CreateNamedPipe 'create a named pipe
ConnectNamedPipe 'listen the client connect request
ReadFile 'get client's data
WriteFile 'send client's data
DisconnectNamedPipe 'close the named pipe
CloseHandle 'close the named pipe's handle

//client
WaitNamedPipe 'wait a named pipe to use
CreateFile
ReadFile
WriteFile
CloseHandle

I have been trying to get the this to work and have been successful when using tiff files that have certain compression ilke LZW however I cannot get a tiff file that has compression JPEG Original TIFF 6.0 compression set for it. In fact I cannot bring up this tiff in windows picture and fax viewer! Has anyone else run into this?

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.

problem clalculating hours and minutes

23-Sep-09 2:37

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;
