Hi,

I'm getting the following error 'after' obfuscating the C# application I have.

Exception Information:
Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'CMConvert.XMLConvert' does not contain a definition for 'GetInvPercentages'

Obfucation options:

{Anonymizer=High}{AntiILDASM=CompleteImproved}{StringEncryptionMode=Encrypt3DES}{SoftwareWatermark=IT Retail, Inc.}

These are the exact same obfuscation options I've got in all my other obfuscated code.

I don't mind sending you the source code for you to look at if that will help determine why this isn't working. Please let me know.

Best regards,
ct

I'd recommend you to change the Anonymizer settings to {StringEncryption, StubUntouchedMethods} and change ObfuscationOptions.Members to KeepsSerialization or DefaultImproved or Full (that's better for exe's that don't use serialization).

I'm assuming that you meant for me to change StringEncryption and StubUntouchedMethods to False, as well as change Memebers to Full.

I've tried the above and the results are the same.

None of this is making any sense at the moment. Can I send you the source for you to take a look at?

No, I meant to decrease level of anonymization and change the level from High(that's predefined) to choose (set to True) just Anonymizer.StringEncryption and Anonymizer.StubUntouchedMethods options.
Yes, you can send us your spices.project, in this case we can make changes to your project and send you changed project back.

That didn't help. I'm going to zip up and send you the code via email.

Also, please note:

The line of code that's having a problem is:

GetInvPercentages(Convert.ToString((xlRange.Cells[rCnt, 4] as Excel.Range).Value2), ref upcharge, ref margin);

The following line of code does NOT have any problems:

GetPercentages(itrDepartment, itrSection, ref upcharge, ref margin);

I wonder if it has something to do with the call to the spreadsheet. What do you think?

ct

Just send us the executable (original) and referenced assemblies (not system, but probably you're using 3rd party or COM assemblies).
We should take a look how calls to Excel are organized, how they use COM, to give you recommendations.

Guess what? I got it to work with my orignal settings:

{Anonymizer=High}{AntiILDASM=CompleteImproved}{StringEncryptionMode=Encrypt3DES}{SoftwareWatermark=IT Retail, Inc.}

I changed

GetInvPercentages(Convert.ToString((xlRange.Cells[rCnt, 4] as Excel.Range).Value2), ref upcharge, ref margin);

to the following:

string gl = string.Empty;
gl = Convert.ToString((xlRange.Cells[rCnt, 4] as Excel.Range).Value2);
GetInvPercentages(gl, ref upcharge, ref margin);

Now it run just fine at runtime. I'm getting no errors.

Is this an issue with Spices.Net or something that I should expect? Do you still want to see the code?

ct

Coud you send us the assembly with GetInvPercentages(Convert.ToString((xlRange.Cells[rCnt, 4] as Excel.Range).Value2), ref upcharge, ref margin);?
Probably Anonymizer in the process of anonymization made something that changed the code behavoir.

Sure, I'm putting an email together for you right now. You'll receive it shortly.
