I have to pack and unpack a 16bit Int from/into a Ushort in VB.net This is how I thought I could do it (doesn't work, gives me overflow exception)
'Pack Int16 into ushort '
Dim usPacked = CType(Data, UShort)
'unpack Int16 from ushort '
Dim unpacked = CType(data,Int16)
c# 's ' (ushort)0x0090 ' equivalent in .net?

View 4 Repliesdealing with a C++-DLL I get a pointer (thepointer as IntPtr) to an array as return value. The pointer indicates the first bit in memory where an array of UShorts is stored. I know the size (thesize as Integer) of the array and want to read it. Marshal.Copy does not support UShort. As the values stored in the named array can exceed 32767 working with Shorts will not do. I tried to work with structures but the array of UShorts in my structure is not populated using: [Code] Does anyone have an idea how to get the array of UShorts out of the pointer position or see a mistake in my code?

View 4 RepliesI am working on fixing a bug in VB that is giving this error. I am new to VB, so there is some syntax that I am not fully understanding. The code that is throwing the error says:
.Row(itemIndex).Item("parentIndex") = CLng(oID) + 1000000
I understand that adding 1000000 is too much for an int16. I can't change that value (not right now anyway). What I don't understand, and can't seem to find, is what .Row is referring too.

(using vb.net) On our intranet site we have an app that loads customer or vendor information and then allows the users to edit info and add/update/delete contacts. I'm not sure what really changed to this program lately, but I keep getting this error:
Method not found: 'Int16 DBLayer.DBTools.ExecuteNonQuery(System.String, DB)'.
This occurs when i try editing any customer info and the vendor contacts, but the program works when I try editing the vendor info/addy. Here's the program code. There's a seperate program on our webserver that contains the classes used. Here's the main code that calls the classes:
TO ADD CONTACT
M2MInterface.M2M.Customers.AddContact(Session("CustVendID"), txtFName.Text.ToUpper.Trim, txtLName.Text.ToUpper.Trim, Tools.RemovePhoneNumberFormat(Phone), Tools.RemovePhoneNumberFormat(Fax), txtEMail.Text, txtNotes.Text, False)

View 1 RepliesI'm compiling and testing the VB programs in a download from MS of the Windows API Code Pack at url...(which is in VS 2008 and needs to be converted to run on VS 2010). So far I've resolved most of the issues, but a couple are baffling.The code as downloaded for the Taskbar demo refers to icons in the project resources as My.Resources.Green and My.Resources.Yellow and Red. Fatal errors, even though all the help pages say this is the correct way to access them. I got the build to run by removing the "My."; has there been a syntax change between VS 2008 and 2010? When I run the app, I get a message from TaskbarDemo.vshost.exe which says "This demo application needs to register .txt files as associated files to properly execute the Task related features. Filetype is not registered." Does that mean that in trying to debug the app, I have to modify the registry to associate the test program with the .txt filetype?

There is no </p> tag so i cannot parse it completely. Now i have two questions :
1) can this be parsed using httpagility xpath ?
2) i have a function to find text between two strings (getbetween). But i have a doubt - If i use "asdasdasd" and " is it always 100% that vb.net will use the script tag which is just above h3 because there are 2-3 same lines - "asdasdasd"
I haver been struggling trying to match the output of the PHP PACK and MD5 functions.The PHP scenario I am trying to recreate in .NET is this.A 32 character hex string is passed to the PHP pack function. It returns a binary string. At this point both the .NET and PHP methods return values are the same. It works up to this point.The binary string then has a password appended to the end. This result is then sent to MD5 and it returns a hash.
When i try to do the exact same thing in .NET i never get the same result. What i have figured out is if i send a regular string to MD5 (NOT a binary string created from the pack functions) I do get the same result every time both in .NET and PHP.However, if i send the binary string to MD5 in PHP and .NET I get different results.
I have been using these forums regularly for getting on 3 years now, and I must say you are all extremely clever! I am adding in a few rectangle at runtime, but I can't seem to display where I want.
