Jaya Chitra Re: Message Queue Error kubben9-Aug-07 1:40 kubben 9-Aug-07 1:40  One more thing to check and then I will give you the code I use. The queue name is case sensitive. So whatever you created the queue name to be that is what it needs to be in your code. Ben Re: Message Queue Error kubben9-Aug-07 1:59 kubben 9-Aug-07 1:59  Ok here is the code: //outbound queue String outQueue = ConfigurationSettings.AppSettings["outboundQ"].ToString(); // using formatname we cannot check if the queue exists. _outboundQueue = new MessageQueue(outQueue); //config file: <?xml version="1.0" encoding="utf-8"?> <configuration> <appSettings> <!-- Queues must be named "FormatName:DIRECT=OS:<machineName>\Private$\queueName" --> <add key="outboundQ" value="FormatName:DIRECT=OS:server01\Private$\Importer.Inbound" /> Hope that helps.

I can get a file size if it is saved on the hard disk, so I can save the bitmaps then get their size in byte... However, I need a more efficient way: getting the size while the objects are in memory. I hope my question is clear! Naimi Re: Getting Bitmap file size,,, Luc Pattyn8-Aug-07 0:22 Luc Pattyn 8-Aug-07 0:22  the file size of a BMP size directly relates to the bitmap's dimensions. I guess the relationship is bytes = a * wid * hei + b a few experiments will tell you what the values for a and b should be.

When I save the files as gif, I get different sizes - that is what I am looking for. Is there a way to get the size of the images as if they were saved as gif files? (without actually saving them!). What i'm trying to do is to compare two images, and find out if they were identical. Of course, this is a terrible way to do it, however, I need the fastest method (because I have so many images). Plus, it is not a critical matter, so if some images were mistakenly identified as the identical, that is not a big deal. Any ideas? Re: Getting Bitmap file size,,, Luc Pattyn8-Aug-07 1:16 Luc Pattyn 8-Aug-07 1:16  Hi, BMP files are uncompressed, that's why their sizes directly relate to image dimensions. GIF files are LZW-compressed, hence you can't predict the file size. If you don't want to save to disk, you can also save to a (memory) stream. However it remains an expensive operation. Now you are asking a completely different matter: image comparison. When do you consider two images identical? is it you have two Bitmap instances, and their dimensions, and all pixel values are identical ? or is it they both show the Liberty Statue ? or something in the middle ? If you want to check for identical pixel content, this is what I would do assuming a large number of images: - create a dictionary (or Hashtable) - now iterate over all your images, one by one. for each image, create your own hash code; I suggest a function of image width W, image height H, ARGB value of pixel (10,10) and pixel (W/2, H/2) and pixel (W-10,H-10). ARGB value is the result of Color.ToArgb() That was 5 values; you could do hash=(hash<<1)^newNumber for each of them, starting with zero (^ is exor operator) - check dictionary for presence of hash code; if not, create a new List (or ArrayList), add (hash, list) to dictionary, and add image to the new list if hash already existed, you found a possible match and you now must compare the image with all images in the list checking all pixels. To do that, use lockbits and pointers (look it up in MSDN and read CodeProject articles on image processing by Christian Graus).

I'd like to use the EnvDTE.ExecuteCommand("File.Checkin"), and all the commands related to scc (File.AddtoSourceControl, etc ...). But I'd like to know if it's possible (and if yes, how to choose the file that we want to checkin (maybe using a parameter), because with these commands it always refers to the file where the code executes, and that's not what I want, as I have to deal with some files in this code. If it's not possible, how can we use the SCC functions directly in C#, because our program may execute in different environments where different SCC providers could be installed (VSS, Clearcase, etc ...), and it would be so cool to use one unique code to deal with theses SCC, if it's possible, using the native SCC code. The last possibility would be to implement the different COM components of the SCC, and to refer on the Register SCCprovider key to know which one to use, but if something easier could be done I would be so happy Maybe another solution exists that I'm not aware of ? Anyway, thanks. François How to LogOff Locked Computer Muhammad Hafeez Ullah7-Aug-07 23:48 Muhammad Hafeez Ullah 7-Aug-07 23:48  I am working on a project in which I have to Log Off the locked computer. I use SessionSwitch to listen the windows locked event, and I used ExitWindows(0,0) to Log Off. But this API function is not working on the Locked computer. Another stratagy is to first unlock the computer and then use ExitWindows(0,0) to Log Off.But unfortunatly I am unable to Unlock the windows. Kindly help me to solve my problem. Using CAPSLOCK status in StatusBarPanel Sgg2457-Aug-07 23:19 Sgg245 7-Aug-07 23:19  I m using a status bar in the form. In one of the panels of the status bar, I just want set the status of the CAPSLOCK & NUMLOCK, the same way it can be done in VB. But in VB the panel properties has different display value, so it was easy. How this can be achieved in C#??? Thanks in advance... Regards SG (sgg245@yahoo.co.in) Re: Using CAPSLOCK status in StatusBarPanel Luc Pattyn8-Aug-07 0:26 Luc Pattyn 8-Aug-07 0:26  The properties Console.CapsLock and Console.NumberLock provide the necessary information.

Its working. But stil a prob. This is when the application start it detects if the CAPSLOCK is ON then I can display certain msg or so... But I want whenever CAPSLOCK button is pressed then it should update the status of the panel in the status bar. If CAPSLOCK is ON then status bar panel should show ON. If CAPSLOCK is toggled i.e. OFF then status bar panel should show OFF. Something like this... Thanks in Advance...;) ;) Regards SG (sgg245@yahoo.co.in) Re: Using CAPSLOCK status in StatusBarPanel Luc Pattyn8-Aug-07 1:37 Luc Pattyn 8-Aug-07 1:37  Hi, there are at least two ways to keep your status bar up-to-date: 1. on your form, set KeyPreview true; then add an event handler for KeyDown; the handler now will fire for every key moving down; in the handler check for Keys.CapsLock; if it is, use Keyboard.CapsLock and update the status bar; don't try to count the toggles yourself ! 2. on your form, add a Windows.Forms.Timer and let it fire say every second; in its Tick handler read Keyboard.CapsLock and update status bar. The choice is yours, it depends a bit on which of those handlers you may already have for some other reason.

Come to think of it, I would prefer the timer approach; with key events, if your app looses focus, capslock gets toggles, app gets focus back, you will not know about the change (unless you add code to some other events too, such as Activate).
