Re: Sending array through pipe «_Superman_»23-Nov-09 13:57 «_Superman_» 23-Nov-09 13:57  Typecast the array to whatever data type the function to send expects and give sizeof(array) as the size to be sent. «_Superman_» I love work.

I would like to get an output "s0.0000005". Could you please advice me on how to achieve this? Thanks Re: sprintf Richard MacCutchan23-Nov-09 12:18 Richard MacCutchan 23-Nov-09 12:18  See the MSDN documentation on printf format options[^].

Erik23-Nov-09 8:06 Erik 23-Nov-09 8:06  Hi, I am currently trying to insert a picture control with more than 256 colors in a MFC dialog in a VC 6.0 project. However, when I paste the bitmap, the IDB_BITMAP resource looks correct, but when I try to reference it in a static picture control, the color depth is decreased dramatically. How can I display a bitmap ressource with 24 or 32 bit in a MFC 6.0 dialog? Re: Picture control with more than 256 colors in VC6 Dialog? «_Superman_»23-Nov-09 8:38 «_Superman_» 23-Nov-09 8:38  Try replacing the .BMP file that is created in the res sub folder with the high color bitmap file. «_Superman_» I love work.

Microsoft MVP (Visual C++) compare images franckesh23-Nov-09 6:55 franckesh 23-Nov-09 6:55  Hey, I would like to write a c++ program that compares 2 images.In fact, I have many B&W images of a boat. I want to compare the contours, so that I could know how alike the images are. And, I want to be able to know the error percentage after comparing. Do you have any advice or can you tell me any paper or book could help me. Thanks in advance, Franckesh Re: compare images Tim Craig23-Nov-09 9:35 Tim Craig 23-Nov-09 9:35  Go to Google, hit advanced search, limit the document types to .pdf, the websites to .edu, enter your search terms, and hit Search.

Re: compare images Rozis23-Nov-09 11:32 Rozis 23-Nov-09 11:32  Maybe a strange tip: Take a picture (1) and make a copy (2) of it. Now put the picture and the copy in a zip. Write down the filesize of the zip. Nex,t take another picture (3) and put it together with the original (1) into a second zip. Write down the filesize of the 2nd zip. Continue this till all pictures are put in zips. If you have 10 pictures you will have now 10 zips. Sort the zips to filesize. The zip containing your original (1) and its copy will have the smallest filesize. The next zip will contain that picture that resembles the original the most. And so on. How this works: Zip searches for duplicate bitpatterns (this is how compression works). In the smallest zip it finds the most (coz their are 2 identical pics). The picture that resembles the first one the most is the one that has a little less duplicate bitpatterns (it compresses slightly worse). The filesize of the zip is an indicator of the resemblance. Note: You will have to create zips for all the combinations... The theory behind: Colmogorov complexities... If you try this solution i would be pleased if you keep me informed of you results.

If the symbols belong to the project you created, put your PDB file in a folder and give the path to that folder as stated above.

Intially , i have 2 project in my solution (1)Win32 Application- AppServer , (2) Setup project . from this i created an MSI and installed my AppServer.exe to local & remote machine. Now my requirement is , i have to register my application as windows services, so i have added one more project as WindowsService1 from VC++->Windowservice option, i have builded all the 3 project and installed my Setup project , i tried to start my exe from services.msc, but here i am able to see Servicename: Service1 Path: C:\testing\windowsService1\WindowsServcie1.exe not C:\testing\AppServer\Appserver.exe I need my Servicename as : Service1 & Path as C:\testing\AppServer\Appserver.exe i mean my service has to point to my Win32 application exe. Plz thru some light on this Your help much appreciated. Regds Jain Re: Calling another execuatbles from windows service??? Rajesh R Subramanian23-Nov-09 6:25 Rajesh R Subramanian 23-Nov-09 6:25  I'm not sure if you need a third project, just for the sake of registering your executable as a windows service. In my opinion, the setup must have provision to register a program being installed as a service. Have you checked on that? “Follow your bliss.” – Joseph Campbell Re: Calling another execuatbles from windows service??? jain_MS23-Nov-09 7:07 jain_MS 23-Nov-09 7:07  Yes Rajesh, i am able to install a service thru setup project (if i select windows service project template) , THE PROBELM IS: i have solution :testing project1: windowsservice1 (Windowsservice project) project2: AppServer (Win32 application project)---> this is my main application AppServer.exe project3: ServerSetup (SetupProject) If i do run my MSI file from ServerSetup, its installing AppServer.exe to C:\program files\AppServer\AppServer.exe and in Services i have only Servicename: AppServer , Path :C:\program files\AppServer\WindowsService1.exe (instead of AppServer.exe) i hope nw i expained correctly Regds jain
