Importing .xls File Into DataGridView?
Apr 7, 2010I 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

Importing Data From Excel To Datagrid Or Datagridview?
May 5, 2010I have a problem loading big spreadsheets into a datagridview.
I had a similar code as above that i used and it works great if you have say 10000 cells to populate cell by cell.
How ever moving to 2 mil cells is a different cup of tea, the code took more than 7 minutes to load the data, and although the data was perfect in every way, its too time consuming, i cant get it to work faster so I used the datagrid instead.
The sheets needed to be imported is 350,000 cells plus. I used code that works realy great, does the import into the grid and transfers the data to a datagridview within 15 seconds with little resources which put a smile on my dail :) then i saw something and it dropped ...
see code:
[Code].....
My problem is that whenever there are values below the heading of the cell the datagrid displays (null)
No matter what i do even converting the values in excel to text it does not display the heading of that column.
When i paste other text into the cells below the heading (NOT NUMBERS) it shows the data and heading, Only if the "type" of content is the same does it display both the heading and the text that follows in rows below.

Asp.net - Importing Web Service
May 1, 2009I 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?
View 2 RepliesBadImageFormatException When Importing C++ DLL In VB?
Jul 4, 2011I 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" ()
IDE :: Importing VB6 Forms To .NET?
Jul 10, 2009I 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?

View 1 RepliesImporting Class From C++ Dll?
Dec 11, 2011Ok, 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?

View 3 RepliesDifferences About Importing Namespace In C# And VB?
Sep 16, 2011In 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)
