I have been searching but unable to find any code examples of using a GPS coordinate to navigate to another GPS by road way. Is there a dll from MS Streets and Trips or any other software that would allow this to happen? This would also need to be done offline, so no Google or other online serive call outs.
View 1 RepliesI am trying to understand how to interact with external DLLs written in C++ for use in my VB.NET application. I have some DLLs that a client wrote that do some math functions. Everything was working on a 32-bit machine. Because we were taxing the 32-bit machine we moved to 64-bit. Now we can't get the same functions to work. The DLLs were re-compiled as 64-bit DLLs and they still don't work. So my client wrote some dummy DLLs to see if we could figure out the problem. Here are the "signatures" of the DLL calls that I am making:[code]....Ultimately I would like to get to calling initialize_quiet and I am guessing at the format of the marshalling, const size etc.
View 3 RepliesI don't know what you would call it but I want to do something like this:
I have a list that contains the following and will have more in the future.
{buffalo}
street
street2
street3
{end}
[Code]...
The problem at hand is to search an Access database for "duplicate" street addresses, given user input of street address, city, state, and zip code.Given the zip code, city and state do not need to be looked at.
My thought was to select off records in the database with the zip code that matches the input, then loop through those records, performing a "similarity" test on the street address field as compared to the input street address. Obviously we cannot test for exact matches (i.e. "SW" vs. "South West", etc.). This problem has obviously been solved before with post office software, algorithms used by mapping applications, etc.
But do you have any thoughts on what algorithm I might implement in a VB 2005 app?
Almost every example of MVVM I found is coded in C#, are there any examples/tutorials coded in VB.Net? I'm having a hard time translating C# to VB.Net since I haven't really used C# in any meaningful way...Also, does a MVVM Template/Toolkit for VB.Net exist yet?

I'm a student taking a beginner computer programming course. My teacher told me to use this website if I have any questions. The lesson I have just studied is about the different types of applications in VB.NET. My assignment asks me to "Give at least five examples of each type of application." I'm supposed to do a web search to find these. The different types of applications I'm supposed to find examples for are: Console, Window, Web, Class Library, Control Library, and Smart Device. Then I'm supposed to provide a description or a screen shot of each example.
I hope my question isn't considered too simple for this forum, but I don't know what else to do! I've spent a long time trying to search for examples myself and I can't seem to find anything.
I hope someone can help. I was "volunteered" to come up with an application for a local charity group. What they are looking for is a system that will track[code]...
They picked me to help as I have done some computer work and for them that means I'm an expert.What they want is for me to use a Visual Basic front-end talking to MySQL. I know enough to realize that most systems DON'T work out first time and the chances are even less if that person (Me) has not much experience.

View 1 RepliesIt is really too bad that Microsoft (who once had the best documentation in the business) has slipped so badly. Good documentation does not really require analysis, though, admittedly, it is a lot of work. To wit: for each and every single method, function, event and operator provide the following: a brief topical functional description including any parameters, a detailed description of how the object works, a workable example of the code needed to make this object do something useful and links to all possible associated objects (See Also).
I see pages upon pages of useless text and links to other pages full of links. This rapidly descends into a crevace of unbelievable complexity for the developer trying to find out something truly simple like filtering a DataGridView without changing the data connection. (As it turns out this is very simple to do but I could not find a single example of how to do it in the Visual Studio documentation.)
Is there any specific reason why camel casing examples often start with a lower case letter?
E.G:Dim btnSave As New Button
'as compared to.>>
Dim BtnSave As New Button
Is it to make a distinction between the ( object / variable ) and its TYPE?
Why then does the IDE not add items starting with a lower case letter if lowercase initial lettering is more common or more accepted?
I've seen quite a few questions about calling 32 bit ActiveX components on 64 bit platforms - as I understand it you can't create a 32 bit ActiveX component from a .NET application running in X64 (native) mode. This is OK and I think I understand it.But my question is more basic. Is there such a thing as a 64 bit ActiveX component? or is ActiveX always 32 bit, period?

straightforward method of creating a DLL with properties and methods exposed to other programs? I followed the instructions that I found on the MSDN websites as well as suggestions from forum participants. The DLL should be available both for COM and .NET programs. So far, nothing has worked.There are numerous variations listed on the MSDN site. No doubt there are reasons for the differing instructions. However, I have not had sufficient success with any of them. Sometimes, just building the project makes the class visible to COM compatible programs. Other times, only after running regasm. Still other times, I have to run regasm, sn and gacutil before the DLLs class gets exposed. Then forums posters tell me: "you shouldn't have to do all that.

You developing a application named "DemoSoft" which is going to be a shareware or Premium, you use different DLL's in this project and some DLL's are owned by you, they are very useful and valuable, you are selling this software and are charging the customer for what the software does but since this software uses one of your Valuable DLL, actually few functions from it you have to deploy it and cannot additionally charge for the whole dll. since that would be unwize.now i want to ask what can you do so that This DLL in "DemoSoft" cannot be exploited, meaning end user could use my software but if some thief tries to use my supplied DLL in one of his own app he is unable to do it, in simple terms DLL should work only and only with DemoSoft.
