IDE :: Importing VB6 Forms To .NET?
Jul 10, 2009
I inherited a DLL project developed in VB6; this project has to be integrated to a VB.NET GUI. At the moment, the project is integrated succesfully except for one detail that it is taking a lot of my time.
Every time that has to load a form from the COM DLL, the execution of the program loops and gives an OutofMemoryError -- I imagine the error is because the executing is looping by trying to load and reload the Form1 from the DLL. So, is it possible to import graphical controls and components along the DLL, such as Form1? or, do I need to separate them in order to import the DLL succesfully?

I am building a small Windows Forms application. I need to 'read in' CSv files into the application.
I am using StreamReader to read the CSV files into the application. That is no problem. On my Form I have a text box, 3 Buttons and 2 data grids. With the first 'browse' Button I am using OpenFileDialog to select which CSV file I want to display in the first grid.
Then I want to use a 'convert' button to display the information from the CSV file in a much more 'user-friendly' manner in the second grid. Lastly I want to use my 'export' button to export the converted file to excel.

I am trying to make part of a form program do the following When I exit a text field, I want to import some datainto a datagridview control.The columns are (1)Key, (2)Location, (3)Part Number, (4)Serial Number, (5)Description.There are up to 1000 rows of data in anyone of the spreadsheets I am working from.By using a datagridview, I can click the header and sort the data by either of the 5 columns, and when I select a data row, the Key number is reported back (for now, into a text box)I will be using the key number to further manipulate the spreadsheet after I have solved this problem.There are thousands of articles on DataGridView, and over the past 8 days, I think I have read them all. I have tried many downloadable routines, which haven't populated the DataGridView at all.Please can someone show me a simple program which will do the above task, and will give me a base to start from.I am running MS Office Pro plus 64-bit on Windows 7 and Visual studio 2010 pro

for example i have a.exe and b.exe ( the a.exe is an vbApp, and b.exe is an executable file ), now.. it is possible to include the b.exe into a.exe and then running it from a.exe, for example importing the b.exe into vbProject and then running it without extracting it.

I have a form that allows a user to import a spreadsheet. This spreadsheet is generally static when it comes to column headers, but now the users want to be able to include an optional column (called Notes). My code crashes when I try to read the column from the spreadsheet if it doesn't exist.
Dim objCommand As New OleDbCommand()
objCommand = ExcelConnection() 'function that opens spreadsheet and returns objCommand
Dim reader As OleDbDataReader

I have created a web service in a virtual directory using VS 2008. I have tested the service by going to the .asmx page and everything is working fine. So I selected the "Add web reference" option under the solution and typed in the .asmx URL. It found the web service successfully and added the reference to the project. However, when I try to import the service namespace using the same name as the directory under the "App_WebReferences" folder, it doesn't recognize the name and gives me an error if I try to import it. Have I missed any steps in the process?

I am trying to write my first DLL and am struggling to get it working correctly and am receiving a variety of errors. For my Hello World DLL I was trying to follow this page [URL].. but as it was very old and referring to VB 6 I am now trying to use the instructions on this page: Essentially, what I have done is to follow all of the instructions on the second link, but then instead of calling it from C++ I call it fro my VB application (I have successfully managed to call DLLs from VB in the past). When I try to call the Add function (or any others) I get a BadImageFormatException error thrown saying "An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)" but I don't know what I am doing wrong. I have tried calling an alternative C++ function that is declared as a void and takes no arguements in order to completely avoid the problem of matching the data types but I get exactly the same error.
I gather that this is sometimes to do with target architectures, and have tried setting the C++ compiler to build it as both a Win32 DLL and as an x64 DLL, and each time changed the VB settings to match the outut type of the other but this doesn't seem to make any difference, and for some permutations even makes it worse with it saying that it can't find the entry point in the DLL that I'm calling.
I am completely new to this and am now at a loss for what to try and what could be going wrong,. The VB import is as follows:Private Declare Function Add Lib "DLL_Test.dll" (ByVal a As Double, ByVal b As Double) As Double Private Declare Sub HelloWorld Lib "DLL_Test.dll" ()

Ok, I've been fighting this for days and so far haven't found very much helpful information on the web. Apparently this isn't a very popular thing to do since there isn't much out there. I'm hoping someone here can help me out. I don't know very much about dll's or implementing classes in vb, so please correct me if my thinking is wrong.If it's relavent I'm using Visual Studio 2010.I'm working on a much larger project, so I've created a greatly simplified version to test and and ask questions about.Here's the situation:I've created a class in c++ that I now need to create an interface for in vb. As I said before I've created a much simpler class and compiled it as a dll. There are two functions in the dll:
[code]...
The setTestVar function simply sets the value of a member variable, and getTestVar returns the value of that variable. I load the setTestVar function from the dll like this:
[code]...
Then when I click a button, I call:setTestVar(9) This results in an "AccessViolationException was unhandled" error. "Attempted to read or write protected memory...."After thinking about it, I guess this would make sense if the constructor in the dll was never called (and thus the variable into which I'm trying to store data doesn't exist).So the question becomes, how do I call the constructor in the dll from vb such that I have some sort of handle or reference to that object when the call returns from the dll? Without a handle, I won't be able to access any of the member variables. Is this thinking close to being correct? Or is the problem something entirely different?So again, how do I call the constructor in the dll (from vb) and somehow have access (from vb) to the object that it creates?

Is this possible? I upgraded to VB Express 8 and have several programs that I would like to import into VB Express 8 from VBE 5. But everything I have tried so far has not worked.....This is the first time I have imported files from one computer to another. I have tried to save the file as a zip file and unzipping it in VB 8, but that didn't seem to work.

I'm trying to import the WinLicense SDK, but When I try and add it as a reference, it doesn't seem to work. It says it's not a valid COM reference. I was just wondering if any of you guys protect your programs with WinLicense, and how to protect my applications with it... I'm trying to use the APIs so I can use the HWID Protection.

In VB, when we adding a new references - in my case web references -, it simply type namespace followed by the class name to make a new object.For example:
Dim obj As NamespaceName.ClassName = New NamespaceName.ClassName
Then I apply this concept in C#. So my code will be:
NamespaceName.ClassName obj = new NamespaceName.ClassName
...and it doesn't work.Actually, is there any difference about Importing Namespace between those two?And also can you give me a little explanation about Project-Wide Default Namespace Imports in VB?
UPDATE:My point is why "In C#, When I've typed NamespaceName, the ClassName was not listed in the Intellisense?".However, it did well in VB, do I have to import something?Maybe, there is something to do with the term "Project-Wide Default Namespace Imports". (CMIIW)

I have a VB file that imports System.IO, but only uses it is a couple of places.My co-workers and I were wondering if there is a small performance boost if we just use System.IO explicitly were we need it (IE., System.IO.MemoryStream) instead of importing it.

I have a datagridview on my form with 7 columns and a variable number of rows. It's used to track stats on games (kills, deaths, assists, etc.) The way I ended up saving it was in a .xls file for the simplicity of being able to edit it in excel as well as my program. how to import the file back into the DataGridView though.
Here's the code I'm using the save the file:
VB.NET
Private Sub exportExcel(ByVal grdView As DataGridView, ByVal fileName As String, _
ByVal fileExtension As String, ByVal filePath As String)
' Choose the path, name, and extension for the Excel file

I'm trying to write a small application that imports data in a column from a csv file into a table in access. I'm very new to programming, but this is what i've come up with so far. It runs, but it's not actually bringing the data over to my database.
Here is the code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim dbPath As String
dbPath = "f:db1.mdb"

I am using VB 2008 for this little first game I am trying to make. Currently a grid of rectangles is being generated when a button is pressed and when you click on the grid I am attempting to import the relevant image into the selected rectangle. Looking through the available options I can't find anything relevant to import the image onto that selected rectangle. Is there another method of importing onto a code generated grid? my current relevant code is: brackets, its my first time here.)
If Form1.MousePosition.X < rect.Location.X + rect.Width And Form1.MousePosition.X > rect.Location.X And Form1.MousePosition.Y < rect.Location.Y + rect.Height And Form1.MousePosition.Y > rect.Location.Y Then
