I'm creating a project with an Add-on system, and I'm releasing an API so people can develop for my application (its called Levanta, its a basic Sub-OS, and i want people to be able to develop for it). I try to call a sample DLL i made to test out the system i created. Well, i CANT, because its not finding the functions entry point of the said function (its named initialize)...?
View 6 RepliesI am unsure why all of the sudden i am getting this error every time i compile and run my VB.net program running Oracle 10g. It ran fine many times but all of the sudden keeps saying this now.

It happens on this line:
myConnection = New OleDbConnection("Provider=OraOLEDB.Oracle;Data Source=(DESCRIPTION=(ADDRESS_LIST=" & _
"(ADDRESS=(PROTOCOL=TCP)(HOST=" & dbHost & ")(PORT=" & dbPort & ")))" & _
"(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=" & dbServiceName & ")));" & _

Once it gets to the myConnection.Open() is when it displays that error box. Like i said, i used to work just fine.
I want to calling visual basic dynamic link library in visual basic applications. I'm using visual studio 2005.net
View 2 RepliesMy program used to run on my system just fine until I removed some other applications. Then the proggy was giving me a runtime error. The funny thing is that once I installed visual basic 6 and added a reference to dao360.dll, or the Microsoft DAO 3.6 that the program then worked without error.
VB6 was never installed on this system before. The program worked just fine until applications were uninstalled from the system. What happened that caused the reference to stop working? Why did the program stop finding dao360.dll even though the program itself wasn't modified since vb6 wasn't installed?

DLL should be win32 standard dll or .net dll.
How can I run the exported function if I have the address of it through GetProcAddress().If someone could supply some code it would be great.

View 4 Repliesi know it might be impossible to achieve (as i've been reading from another articles) but does anyone know how to set a dll entry point in VB.net project? I have created a VB.net dll and trying to call that dll from cobol (unmanaged code). in Cobol, i can only use the entry point statement to call VB.net dll (cannot add reference to it). as consequence, i'm getting "called program not found" (or in VB error is equal to "can't find dll entry point")
View 2 RepliesI was playing with VB.Net yesterday using Visual Studio Express (VSE). I am trying to get a feel for the language. One thing that struck me was the fact that VB's entry point, Sub Main(), is written inside a Module, as opposed to inside a Class like in C#. At least that's how it appears in the books I'm reading. That got me thinking. Is it possible to change the entry point location from a Module to a Class, or for that matter to have Sub Main() completely outside these two constructs?
I search the internet and found out that VSE indeed allows one to changed the entry point through the project properties. So I set the entry point to Sub Main() and tried compiling the "Hello World!" project locating Sub Main() inside a Class construct. Well, that didn't work. I tried changing the name of the class to match the project name, but that didn't help. I didn't bother try putting Sub Main() completely outside a module or class figuring that would be impossible. However, while looking through various post in this forum, I got the feeling I gave up to soon. So here are my questions:
1. Can the entry point be within a Class/Form construct or completely outside any construct for that matter?
2. Can the entry point be some other Sub (e.g., Sub MyMain)
If the answer is yes to anyone of these questions, where do I set the option to make this work?
Recently, I upgraded VB6 project to VB.Net. After that I can sucessfully compile the project and generate a DLL file in the bin folder, but when I try to use regsvr32 command to register the DLL, I got error saying "DllRegister Server Entry Point is not found".
And I cannot remove it from memory, if I want to use my old DLL.
I have written an application that calls 'My.Computer.FileSystem.SpecialDirectories.Currentm UserApplicationData'. My application is working fine, but one user has reported an issue that has me stumped. When this property is accessed, the following exception is thrown:
"Unable to find an entry point named 'VerLanguageName' in DLL 'version.dll'". The stack trace says that the exception came from Microsoft.Win32.UnsafeNativeMethods.VerLanguageNam e(Int32 langID, StringBuilder lpBuffer, Int32 nSize)
I don't think the problem is with my code. I suspect that there is something wrong with a system-level component on her computer, particularly with the DLL that is mentioned. Is this DLL part of a specific windows component that could be reinstalled/repaired?
I need to create a COM-callable DLL using VB.NET 2010 that can be opened by a legacy VB6 application. I'm experimenting with a very simple demo example first. When I try to register the resulting DLL with regsvr32, it shows me this error:"DemoCounter.dll was loaded, but the DllRegister Server entry point was not found. This file cannot be registered."Here are the steps I followed:
1. Create new VB.Net project as a class library.
2. Delete the class1.vb file it starts with.
3. Add a new class from template "COM Class"
4. Build the DLL and try to register it.
The class has the GUIDs, the <COMCLASS ...> stuff, and has a checkmark in the "Register for COM Interop" checkbox of the project settings.[code]
I have created a dll using class library in visual studio 2010. This dll calls another dll to perform some special calculations. I want to deploy the whole setup in excel vba and it had worked properly on the PC, on which I have generated the dll. The top cover dll is automatically registered in the registry list and i did not use the "regasm" to register it...
Now when i try to use this on a different PC (Win7 x64 OS, No Visual Studio), I'm facing problems. I am unable to register the dll with regasm, as I dont have it. When i use regsvr32 i get the Error "dll was loaded but DllRegisterServer entry point was not found"

I seem to have a problem with my DLL Function call test. I don't usally use orums...but...this is racking my brains and I need to know fast! I have searched and searched google, but I have no answer, (I do, but don't understand very well).I have created an application called epsControl.exe in Windowssystem32 folder. I have also created a file called epsDevDrv.dll or EPS Device Driver. It doesn't really act as a device driver, I just gave it a fancy name, (that's why I'm called the VB Weirdo.........) anyway to the point:My dll does a simple function, to answer a mathematical problem (simple), and return it to the exe file which puts it in a msgbox.
