View 6 RepliesI have some code that was written in C# and am attempting to convert it to VB.Net, for the most part things have gone well but I am running into an issue that I am not sure how to handle. The project has several classes and a few namespaces defined. The issue is [or seems to be] related to the namespace usage.
In the C# code of one class I have
Code:
namespace GdiPlusLib
In another class I have
Code:
using GdiPlusLib;
When translated to VB I have in the first class above
Code:
Namespace GdiPlusLib
and the following in the other class from above.
Code:
Imports GdiPlusLib
I get the following warning message on the imports line
Namespace or type specified in the Imports 'GdiPlusLib' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases. There is another instance with a different namespace that gives the same warning and I get 11 errors all of which would seem to be related to the two warnings.
I am wondering if VB.NET has the "|=" Operator that is present in CSharp or if it goes by another name.

1.Take an file(exe,dll,etc)
2.Convert it into hex
3.place that hex values in a stack
4.Execute the values inside the stack to its original form(i.e. take the elements out of stack and then convert it to a compile format)

I have what might be a dumb question, and/or discussed at length back in the 2005 days, but I could not find anything on it. Sometimes Google Fails me I am moving a old vb 6 application to .net and I hit a roadblock on ADODB. Now I used the converter to see what the effort was going to be and the first thing I noticed was that I could no longer bind my Text Data source like I used to.

I have visual studio 2010 Ultimate, but I cant convert a vb6 project easily. I just downloaded and installed the vb2008 express because I know it should have the capability to upgrade/convert it with reasonable accuracy.
I am getting this error:
unexpected exception occurred during upgrade engine operation: not able to bind to the source (exception from hresult: 0x8004000a (ole_e_cant_bindtosource))
We are currently running a 32-bit VB.NET 2005 application with a 32-bit SQL 2000 data store. The network guru is going to be upgrading the server and SQL to a 64-bit version on both. Will the 32-bit application still connect to the 64-bit data files? I am guessing I will somehow need to tie in the 64-bit drivers somehow, but will those work on a 32-bit development system?
View 4 RepliesI was converting my VB6 codes to VB 2008. There is a section i use a third party application (Microsoft Excel) to print report. But now VB 2008 is not accepting one of my statement. the statment is shown below in bold letters.
oSheet.range("H" & Row & ":" & "J" & Row).Value = Array(InvoiceNo, , Today)
it works in VB6 but fails in VB 2008 because of the Array statement, is there any replacement for this in VB 2008.
I have been converting my VB6 programmes to VB 2008. many of the problems that came up I have been able to solve; mostly by trial and error. However, I have one problem that was easy to handle in VB6, but I don�t see how to do it in VB 2008. I have checked Google, but didn�t find anything exactly similar to what I want to do.
On my form in VB6 I added two text boxes, each with it�s own name. I then copied these two and pasted them back onto the form, under the original textboxes, 5 times. Each time I was asked whether I was creating an array; I confirmed that I was.
I could then code as follows:
For x = 1 To 6
BidderName(x) = txtBidderName(x)
BidderCommunity(x) = txtBidderCommunity(x)
[Code]....
I tried to do the same thing on my VB 2008 form, but it does not ask whether I was creating an array, and in fact the array of textboxes on the form, is not an array!
how I get around this. The form has to show an array of textboxes, which are entered in order.
I converted vb6 project to vb.net 2008 but I got some error first one :Name 'VarPtr' is not declared.I got this one two times :Value of type 'Projectname.Func.EXPLICIT_ACCESS' cannot be converted to 'String'.

View 2 RepliesI'm having some trouble converting the format of a date in .NET 2008...
Dim currMonth As Date
currMonth = Format(Now, "mmm")
From this code, I need to extract today's date in the format of "mmm" (so it should return.. "Apr")This worked in vb6 but not in .Net, I keep getting some sort of conversion error.. I looked at using theformatdatetime option but it doesnt have the format that I need... only short date/long date...that kind of thing.
I have an application that was developed and is maintained in VB.NET 2003. Is it possible to convert the 2003 files to Visual Studio 2008 and maintain the program in 2008? If so is this fairly easy to do?
View 4 Repliesi have to get this off my chest.Forgive me... I'm a relative newbie stuck in the vb6 world because of my job.vb6 to vb .net is a huge change in the way one has to program (and to think). I never could figure out the big picture of things with .net.Everything is a class..? What's with all of this... Class this, Interface to a class, inheritance (of classes) here, casting? polymorphism.
As a newbie to vb.net (I use 2008)... I just wanted to say this out loud and see if i can even get my terms correct. Vb6 is a good language for beginners but not a real professional language and (vb6) is effectively a watered down, lazy man's (quick and dirty) way of creating programs to solve some particular task.

I have some byte whose values are 00 09 and I'd like to convert the values to bits to be like this : 0000 0000 0000 1001. Then I'd like to read the value of first 2 bits and the remaining 14 bits separately.

View 5 RepliesI have made an application with a client, server and listener. The server is a console app and the other two are Windows Forms Applications.
Basically i am using a Network Stream to send messages from the client which go through the network to the server which bounces them to the listener which then reads the message and tells the app what to do. (For example if i sent "shutdown", the listener would read it and then execute "shell(shutdown -s)".
The messages are sent like the following SendMessage("shutdown") but when i use a screen capturing API and send from the listener to the client like so SendMessage(background) i get the following error:
Quote:
Value of type 'System.Drawing.Bitmap' cannot be converted to 'String'.
This program, it reads in a file, and displays it in hexadecimal, like using a hex editor. It then goes to compare the strings and whatnot, and display certain values. During the program, there is a time where I need to display a set of offsets as decimal because that is the way that it is shown regularly.
Taking the two specific offsets and displaying them in hex ends up giving me something like "3039" or "000A", which should respectively convert to 12345 or 00010. This "ID" that I am converting, can be 00000 to 65535, which in hex is 0000 to FFFF. The current method I was given only works if the value is less than 512 or something like that.
