Debug "wrong Number / Types Of Arguments In Call" Errors?
Nov 24, 2009So I've recently been vexed by problems similar to this one: Oracle .NET error - Wrong number or type of arguments. I know oracle is famous for its terrible error reporting, but this is a giant pain to debug -- if you have ten parameters, that's twenty things to check by hand (types and names,) not to mention the actual number of parameters, and if they're actually legitimate values.
Is there some way to get better diagnostics on stored procedure calls to oracle?
Call Error Message : "Too Many Arguments For ListItem.ToStringDelegate"?

Winapi - Closing A Modal Popup?
Dec 15, 2009I want to wait for and close a modal form (a popup) from another application, as soon as it appears. I want to do this from VB.NET, but suggestions in C# should be easily translateable.
I can hard-code the modal popup's caption in my app, since it's long and unique. What I want to do is simulate either the user clicking on the close ("X") button on the form, or a click on the defeault, tab-order 0 button of the form. Either would work.
Maybe I need more info about the modal popup other than the title bar's caption? In any case, it's safe to use it as an unique identifier of that modal form. I also want that code to terminate checking as soon as the first event of closing the popup happens.
I believe it's trivial, but I can't find any ready info on that. Microsoft says I should not send WM_CLOSE to the modal popup, since it will call DestroyWindow() instead of EndDialog(), but to be honest I don't even know what "sending WM_CLOSE" to the "window" means =/
Hooking Another Program's Calls To Winapi Functions ?
Oct 22, 2010I have been trying to build a game bot in vb.net.One of the main problems is getting access to the text the game prints on the screen so I have been trying to hook the games calls to the windows api drawtext and textout functions.I have been hunting for examples of how to set up a hook in vb.net for a long time without any luck.I have found it impossible to translate examples in old school vb, C++, and C#.For convenience's sake I would like to use the freely available deviare and/or easyhook libraries.
View 2 RepliesPassing Winapi 'HANDLE' Type Between VB & C Code
Feb 23, 2011I have written some C/C++ code that uses the winapi functions CreateFile WriteFile SetFilePointer etc. to read & write some large (>4 GB) binary files. Some colleagues who are more familier with Visual basic than C, want to modify some of their existing code to call my C code functions.
I have turned my code into DLLs that I have successfully called from other C programs. I have also created a small C DLL that doesn't use the winapi functions & called it from a small VB program.
What I haven't so far been unable to do is pass the HANDLE type variable between a C function that uses the winapi functions & the VB program that call it so the VB can call another of my functions & pass the HANDLE.
In my attempt to do this, the declarations in the header file for two of the functions in the C DLL are:

When I step through the VB code in debug mode there is no problem with calling OpenSegyRW, but at WriteToSegy I get the error message:System.Runtime.InteropServices.MarshalDirectiveException was unhandled

Jun 8, 2012I have a timer in winforms that looks for a specific OK dialog on my server (it clicks OK on a third party application that runs out of memory, then restarts it -- there is no other work around). So, when I remote desktop the server and the remote desktop window is active (the actual remote desktop window is active, not the actual window that has the OK that has to be clicked. I can have a window that has nothing to do with the OK, and it works), the program works as it should. It finds the window of the OK, then clicks the OK button fine. When I am not in remote destop, or when the remote desktop window is not active (or selecte) it finds the window and finds the OK button, but cannot click the OK button.

Function Syntax - Call A Function With 2 Arguments When The Function Is Only Defined For One
Apr 1, 2010I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for

.net - Use Attributes And Including Arguments?
May 17, 2009I'm writing a class-library in VB.Net and one of the subs that are being called from the application which is using my library has more or less the following syntax:
Public Sub LoadDict(ByVal PhoneticType As String, ByVal strDict As String)
where PhoneticType can be phonSoundex, phonDoubleMetaphone or noPhonetic
I want to give the application-developer a possibility to select the PhoneticType from a list when writing the call of above sub (I think it's called attribute-arguments). This would make it easier for the developer since spelling-errors can be avoided and which will avoid errors when using the library. I think it's all about attributes but I haven't managed to get it to work despite trying.
