In the original, the code is using textLen, not text.

When you say "not working" what is not working? Remember, I can't see your screen, just what you tell me.
Check your logic - I notice that your loop is different from the C++ version which misses the first char if the string starts with '"' - yours ends the loop when it meets the first '"'. And please, don't use "magic numbers" - they make code really difficult to follow and maintain.You should never use standby on an elephant. It always crashes when you lift the ears. - Mark Wallace

not working mean, it suppose to return D18AA035 for B5_CUT2_1 but its returning 334A644A

}
34, 65, 25, 92, 47, 32 - these are all "magic numbers". Wiki - see Unnamed numerical constants here.[^] So called because they are necessary to the code but there is no explanation as to what the hell they are or do!
Looking at the original C++ code there is also a magic number 32769 - why? Does this have anything to do with the length of an int?
I am not convinced that the original code actually works (or even compiles): what is textLen[i] doing? textLen is a size_t (which is an unsigned int) not an array.
Try this[^] - I don't know that it works, I haven't tried it, but it is at least written in C# and looks like a CRC32 algorithm!You should never use standby on an elephant. It always crashes when you lift the ears. - Mark Wallace

That code is for specific CRC...I dunno why the author did that...I just got the code from a site that says its for that purpose(I need) so I simply tried to convert it to C# but I thought I may did something wrong. Thats why I asked here.

| If you have to use this specific code for a specific purpose then the original author is naughty to call it CRC32 if it isn't. The best way to proceed if you have to use this code and no other is to compile the C++ code into a managed DLL and include that assembly in your C# code - then it will only generate the wrong results if the original code is wrong as well!

yupp I thought of that...but now I got the bug in the written code (C++). So all working fine now.
Btw, I can see somebody voted you 1. It wasn't me

Didn't think it was - it's just an idiot you who thinks he's clever - I'm not bothered!

Sorry about that! Typing error caused by insufficient coffee! Was intended to read "who thinks he's clever" - fixed now.  You should never use standby on an elephant. It always crashes when you lift the ears. - Mark Wallace

In your first sample the line
char ctext = textLen[i];
will produce bogus results. I think you mean to select the next character in the text string, the above instruction will pluck some random value from memory.txtspeak is the realm of 9 year old children, not developers. Christian Graus

Hi All,
I am using Asp.Net 2.0 with C#, Crystal Reports(VS 2005). I am trying to open a report by passing 4 parameters but it gives an error called "Object reference not set to an instance of an object.". While I debug, I did not get err at any line. It goes smooth but finally it gives an error. Can you guide me?. Pls find below my code
crvSTT.RefreshReport();
ReportDocument rptDoc = new ReportDocument();
rptDoc.Load(Server.MapPath("Reports/STTCertificateAnnual1.rpt"));
ParameterFields paramFields = new ParameterFields();
ParameterField pfYear = new ParameterField();
ParameterField pfBACode = new ParameterField();
ParameterField pfFromClientCode = new ParameterField();
ParameterField pfToClientCode = new ParameterField();
pfBACode.ParameterFieldName = "pBACode";
ParameterDiscreteValue pdvBACode;
pdvBACode = new ParameterDiscreteValue();
pdvBACode.Value = strUserId;
pfBACode.CurrentValues.Add(pdvBACode);
paramFields.Add(pfBACode);
pfFromClientCode.ParameterFieldName = "pFromClientCode";
ParameterDiscreteValue pdvFromClientCode;
pdvFromClientCode = new ParameterDiscreteValue();
pdvFromClientCode.Value = txtFromCC.Text;
pfFromClientCode.CurrentValues.Add(pdvFromClientCode);
paramFields.Add(pfFromClientCode);
pfToClientCode.ParameterFieldName = "pToClientCode";
ParameterDiscreteValue pdvToClientCode;
pdvToClientCode = new ParameterDiscreteValue();
pdvToClientCode.Value = txtToCC.Text;
pfToClientCode.CurrentValues.Add(pdvToClientCode);
paramFields.Add(pfToClientCode);
pfYear.ParameterFieldName = "pYear";
ParameterDiscreteValue pdvYear;
pdvYear = new ParameterDiscreteValue();
pdvYear.Value = "Current";
pfYear.CurrentValues.Add(pdvYear);
paramFields.Add(pfYear);
crvSTT.ParameterFieldInfo = paramFields;
crvSTT.ReportSource = rp.tDoc;
crvSTT.DataBind();
Thanks in Adv.Balasubramanian K.

| Your message got posted twice, please delete the previous one. You do not indicate which line of your code gets the error so it is difficult to guess why it is going wrong.

All of my code lines are getting debug successfully without any error.
But error has been shown at my page by debugging all of my lines. Thanks in adv.Balasubramanian K.

Hi guys,
I am having a few problems reading a line from an XML file on the web somewhere - say http://www.blah.com/myfile.xml - from within a c# application.
I do not even know roughly where to begin in order to read the XML file?
Do I need to download it to my desktop first, and then open it - because of security issues?
A poke in the right direction (or correct functions / concepts to use) would be greatly appreciated!!
Thanks!
Alex
