Re: Converting a char array containing ASCII values to Unicode string jayshml13-Feb-06 1:30 jayshml 13-Feb-06 1:30  Actually here is what i want to do: byte[] buffer = new byte[buffersize]; baseStream.Read(buffer, 0, buffer.Length); where basestrem is a network stream. now I want to convert this byte array to a string containing unicode values. Re: Converting a char array containing ASCII values to Unicode string Guffa13-Feb-06 4:37 Guffa 13-Feb-06 4:37  Use a streamreader to read the stream with the correct encoding (making the buffer obsolete), or use ASCIIEncoding.GetString to decode the buffer. --- b { font-weight: normal; } how to set datagrid property in form1 from other forms hdv21212-Feb-06 23:03 hdv212 12-Feb-06 23:03  hi i want to change datagrid properties in form1 from other forms .. how to do this ??? i tested some waye (using public modifier for datagrid in form1 or using property to return datagrid properties or method that change datagrid properties from other forms but did't get result) Please Help me how to this ????

Re: how to set datagrid property in form1 from other forms iashishi13-Feb-06 18:05 iashishi 13-Feb-06 18:05  Hi, Any of those methods should work. Just make sure you are not creating a new instance of the form1 to get access to property/public method. Ashish Iddya Auto update msde JacquesDP12-Feb-06 22:30 JacquesDP 12-Feb-06 22:30  My program runs on a sql server database. What I need to do is that when I update the program I need to update the database automatically with the sql script files, is there anyway that I can include the script files inside of the app istaller so that the database is automatically updated. At present what I do is to install the program and then manually via command prompt update with osql. Is there a way that at the time of installation I can run a command to cmd. Any help or ideas will be appreciated. Thanx in advance. Re: Auto update msde leppie12-Feb-06 23:07 leppie 12-Feb-06 23:07  Depends really on the installer. MSI - use a custom action, or learn how to run commands. NSIS - nsExec::ExecToStack '"yourapp.exe" /arg1 /arg2"' xacc.ide-0.1.2.12 Now with more features and one less bug! BSTR to c# string iashishi12-Feb-06 21:07 iashishi 12-Feb-06 21:07  Hi, I have a COM application that sends out _bstr_t to a .NET interop. The strings that I get for ASCII characters are fine in .NET,but I get junk values for unicode characters. Do I need to make any modifications to the string that I get in .NET to display peoper characters? Thanks in advance, Ashish Iddya Re: BSTR to c# string Tulika Shrivastava12-Feb-06 22:30 Tulika Shrivastava 12-Feb-06 22:30  have u changed the project settings to UNICODE in ur COM application???If not then try to change the settings in the preprocessor defition and Project options to Unicode. Re: BSTR to c# string iashishi12-Feb-06 23:14 iashishi 12-Feb-06 23:14  Yup, have done that. The COM application seems to pass the characters correctly. I tried returning the unicode string back to COM from .NET, & it returned the correct string. .NET seems to handle the string differently, if I pass 5 unicode characters, I get 10 characters(all junk but there are 5 commas in them). Any ideas??!? Re: BSTR to c# string StealthyMark14-Feb-06 6:03 StealthyMark 14-Feb-06 6:03  You have to decorate these strings in your .net interop interface/class/struct with a MarshalAs(UnmanagedType.BStr) attribute. Re: BSTR to c# string iashishi16-Feb-06 22:02 iashishi 16-Feb-06 22:02  Tried adding MarshalAs attribute. It didnt make any difference. Here is the code I am using.. public bool CreateFile([MarshalAs(UnmanagedType.BStr)]string file,string app) { FileStream fileStream = new FileStream(file,FileMode.OpenOrCreate); /* write some stuff in the file here*/ } Unfortunately, it is not creating a proper filename if the string is unicode. The above function works correctly if I execute it directly from .NET(without MarshalAs attribut) Any suggestion is welcome..This has me stumped for over a week now.

Mnemonic Talktorajeev12-Feb-06 20:11 Talktorajeev 12-Feb-06 20:11  Hi, I am using Mnemonic with label controls. I have set UseMnemonic true. In design time underline character appears but in runtime , underline character appears only after pressing Alt key not before that. What I am missing? Any clue? Regards, Rajeev Re: Mnemonic Colin Angus Mackay12-Feb-06 20:23 Colin Angus Mackay 12-Feb-06 20:23  Isn't that the normal behaviour. With the exception of Office applications, everything else on my PC only shows the underline when the alt key is pressed. (Office applications, if you didn't already know, are developed using their own GUI toolkits separate from Windows - normally they are a little ahead of the curve, but when the Windows GUI catches up it does things a little differently) ColinMackay.net "Man who stand on hill with mouth open will wait long time for roast duck to drop in." -- Confucius "If a man empties his purse into his head, no man can take it away from him, for an investment in knowledge pays the best interest." -- Joseph E.

Now I am rewriting the whole application in c#. But I am not able to map all the paramters of CreateFont to the Font class of c# and to provide backward compatibility it is important. Can anyone suggest me a possible workaround for this problem ????

O'Donnell Re: Convert MFC Fonts to c# Fonts Tulika Shrivastava12-Feb-06 21:35 Tulika Shrivastava 12-Feb-06 21:35  hi, The information about the font is stored in the follwing format: 1. LoByte (Point size for Font) 2. LoByte (Point size for Font) 3. LoByte(LoWord(Height)) 4. HiByte(LoWord(Height)) 5. LoByte(HiWord(Height)) 6. HiByte(HiWord(Height)) 7. LoByte(LoWord(Width)) 8. HiByte(LoWord(Width)) 9. LoByte(HiWord(Width)) 10. HiByte(HiWord(Width)) 11. LoByte(LoWord(Escapement)) 12. HiByte(LoWord(Escapement)) 13. LoByte(HiWord(Escapement)) 14. HiByte(HiWord(Escapement)) 15. LoByte(LoWord(Orientation)) 16. HiByte(LoWord(Orientation)) 17. LoByte(HiWord(Orientation)) 18. HiByte(HiWord(Orientation)) 19. LoByte(LoWord(Weight)) 20.

HiByte (character of face name) Here the first inforation i.e.Point size for Font is the value which we get from the CFontDialog::GetSize() function and the rest of the information are the the parameters of the CFont::CreateFont( int nHeight, int nWidth, int nEscapement, int nOrientation, int nWeight, BYTE bItalic, BYTE bUnderline, BYTE cStrikeOut, BYTE nCharSet, BYTE nOutPrecision, BYTE nClipPrecision, BYTE nQuality, BYTE nPitchAndFamily, LPCTSTR lpszFacename ). I am not able to map all these parameters to their corresponding c# values and thus cant open the application developed using the previous version( MFC ) and see the fonts properly.Any suggetions??? -- modified at 4:33 Monday 13th February, 2006 Displaying data from text file to dataset mitreviper12-Feb-06 19:37 mitreviper 12-Feb-06 19:37  Hello, I'm trying to display data from a text file "TAB" into a data set for display in the windows form.
