I'm a systems analyst and the company I work for likes to automate as much as they can. Recently I've been getting a lot of questions like "can we automate this in any way?" and I have no idea. I've done automation for Word, Excel, adobe reader and a terminal viewer they use but that was mostly done with code already written by some one else here. If there is a program you want to automate, do you just go to the programs website and hope they have a developers section or is there a standard way to use program dlls for automation? I'd also like some good resources on COM objects if anyone has some, I believe that is how most automation is done, correct?

I would like to use the transactions commit/rollback against a sql server rdbms within a VB 2010 module. I understand how these can be executed within a Transact-SQL session, but cannot seem to be able to code them correctly within VB as these are more like DDL statements.
View 4 RepliesHow to implement resize begin and end on controls the way a Form does. I had the idea that this can be accomplished using windows messages API (WM_ENTERSIZEMOVE and WM_EXITSIZEMOVE) but most of the samples I've seen so far are for windows. The reason for this is because I have a control that needs to re-render an image. The controll is inside a split container. The split container has only the Resize event. Is there any way this can be done?
View 4 RepliesI want to read ALL text between specific <b1> and </b1> tags + hide the tags, example text:As part of the Visual Studio product range, Microsoft created a set of free development environments for hobbyists and novices, the Visual Studio 2005 Express series. One edition in the series is Visual Basic 2005 Express Edition, which was succeeded by Visual Basic 2008 Express Edition in the 2008 edition of Visual Studio Express.[8]The Express Editions are targeted specifically for people learning a language. They have a streamlined version of the user interface, and lack more advanced features of the standard versions. On the other hand, Visual Basic 2005 Express Edition does contain the Visual Basic 6.0 converter, so it is a way to evaluate feasibility of conversion from older versions of Visual Basic.

I want to create a very simple (to begin with) database driven application. The company I work for have very kindly said they will host any SQL database I create, they have a remote server that we all connect to for files etc.

I have an HTML string and in that string are certain variables that I need to replace with database values. The variable names are dynamic but all begin with the characters "@@" (just two ampersands, no quotes). Is there a way to get all the words in a string that start with "@@"? I'm assuming you would use regular expressions, but not sure how to begin.

View 6 Repliesi am trying to enumerate all IPs on my local network, but i am not having any luck. The only thing i have came up with so far is a really tedius "get my own ip and scan the subnet with pings" which surely isn't the best way? I am really only trying to get the ip of a tivo box, and i can determine it's a tivo by mac address or name. My router lists the "computer name" of the tivos as a long string of numbers with the prefix "tivo".What about broadcasting a ping packet? I could also attempt to connect with telnet to port 31339 on every one of them.
View 8 RepliesI'm writing a media management tool and want to add support for MTP based devices.I've been reading through the SDK docs and with the help of some C# examples have managed to make a start on getting some VB code working.
I've come across a few anomolies that I hope someone can help me with!In the examples IPortableDeviceManager.GetDevice appears in C# to receive a string array. But in VB.NET it appears to only receive a string. I have a similar issue with IPortableDeviceManager.GetDeviceFriendlyName which according to the C# samples appears to receive a char array, whereas in VB.NET it is accepting a UShort.
