We have some predefined strings that can be inserted into a text box during data entry via a button click. How can we track the cursor insertion point so the inserted code is in the right place if the user clicked somewhere in the middle of the data before clicking the button?

i 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.

View 2 RepliesI'm trying to extract a piece of text from within the string, defining both a starting point and an ending point. For instance, say I want to search for the text found between "That is a " and " car" in the string "That is a red car", so it would return "red".I know you can use .SelectionStart and SelectionLength, but the length of the word can change, so the selection length can vary. What I want is to establish a specific starting point and a specific ending point from which to extract the text from the string.

View 4 RepliesCurrently we are using a VB script macro created in word to create some fairly simple forms based off of data entered on a data entry form. I am very new to VB, and I have been able to create many applications using forms, but I have absolutely no history creating reports. I have been reading up on the reports, and it looks like they are designed to use with data sources like tables. I merely want to take either data from the entry form, or from data derived internaly from processing the user entered data and populate a defined report "form". I have been searching, but there is so much on printing reports, that I feel overwhelmed. I am not looking for the exact answer as much as a link or place to look for a sample for what I want to do.

That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)
I have an application that receives data input from an automated set of devices. This data stream I have managed to capture & get it into a list box which I can sort based on the Device ID & the time that the response was received.There is a set time window for the devices to transmit their data into the application and during this each device is not limited to the number of responses it can send (ie :- Device 1 can send in 2 responses where Device 3 can send in 40 responses, etc).All of the responses are captured, listed & sorted within the listbox (this bit is working ).I now need to extract the last (ie:- latest) entry in the listbox for each Device ID & this is where I am stuck. I can retrieve the last item in the list but cant seem to extract the last item for each Device ID.[code]
