I am Automating IBM iSeries Emulators using VB.net, created GUI that embeds the external iSeries Emulator Window in a WindowsForm Panel using the "SetParent" API .. To communicate with the iSeries Window I use the SendMessage API to send Key's to the Screen. I am aware of the sendkeys.keys in .net, but this way I dont have to SetForegroundWindow and reactivate my Form.

I have read numerous postings but this is my first contribution. I am trying to use Sendmessage to send a string of text from one application to another. I have created a sandbox to work out the details. I have used the Notepad example and I have gotten that to function. This is what I have that works.

give me a link to an Example on SendMessage/PostMessage? (I want to use SendMessage/PostMessage to send Strings)
View 6 RepliesI've got a curious problem that I can't crack. I have 2 applications, app A and app B. Application A runs continuously doing various things. On the same machine I have application B that runs infrequently at random. I need for application B to tell application A to do something. Both are vb.net apps that I've written and can tweak to make this work. I can't figure out how to get app B to communicate with app A while app A is already running?

I am currently writing a program that must extract data from the screen of another application. This application is a client side database interface. When the client retrieves data from the database it is displayed on this form. I am currently using.

I am developing an application that inserts text into another application. No problems at all finding handles and using SendMessage to insert text into their standard edit boxes/combo boxes/etc.My problem is that when I attempt to insert text into what appears to be a masked
text
box
(e.g. a date into a box with the format __/__/____), it does so...but the application does not recognize it as valid data.How to I format my string/SendMessage to match the mask in the text box?

The project I'm attempting to accomplish has to do with real estate. What I would like to do is go to a URL, automatically enter login information, once logged on, be able to grab certain pieces of text from the page, and then paste those pieces of text into another online application that also requires a login.
That probably sounded a little complicated but basically all I'm doing is putting text into textboxes and then pressing buttons. It would make the job much easier if it were automated.
I searched the forums and found that the webControl module seemed to be the place to start so i enabled it in my Toolbox.

I am trying to use the send keys function to send text to another program.I ahve gotten it al working well, except for using () as I know sendkeys doesnt like these.I have tried using the Replace function in several places in my code to replace the ( with {(} and {+0} etc, with various other options tried.But when I run the program, it seems to skip this out completly and leaves them in the string as (, and therefore it errors and wont run.When I step through it, it goes through the function but doesnt alter the strng as it should.

what WPF based apps are?Is it an application that runs under Silverlight? If so, how?I know; Windows Forms based apps,console apps,DLL _ Class Library Projectsand I've had an introduction to ASP.Net.What I mostly want to know is, if WPF apps are for Silverlight then do they also run in a server based fashion like anASP.NET website would when you create ASP.Net webpages?Is it a way of creating what looks like a FORMS BASED application but it runs in a browser instead or what?Please enlighten me a bit further as I have no idea what WPF is all about.

View 3 RepliesI've designed a Windows Service in Visual Basic 2005 that needs to call some functions from a DLL written in Delphi 5. If I try to add this DLL as a reference, I get this error:
"A reference to 'C:ProjectsServiceProMDPUpdateServiceMessageStubApplicationSPHost.dll' could not be added. Please make sure that the file is accessible, and that it is a valid assembly or COM component."
I assume that it is just not possible to add this DLL as a reference to my VB2005 project, since the DLL was written in an old version of Delphi, correct? This isn't a big deal, as I can just use the DllImport function from System.Runtime.InteropServices, but if it is possible, adding it as a reference would be preferred.
My other question is, how would you be able to call a function from the DLL using DllImport, if the function you are trying to call takes a Delphi record data type as a parameter (if this is possible)? If possible, would I need to pass each field in the record separately or would I be able to define a structure in my VB app that mirrors the record definition in the Delphi DLL and pass that? Or, would it be best if I just created another function in the Delphi DLL that took various string/integer/boolean/etc. parameters that I could call from VB that would then call the original function in Delphi? I tried searching the internet for this specific question, but I couldn't find anything that looked useful.

I've gotten a DLL from a supplier. Most functions I can call just fine, but some crash (System.ExecutionEngineException, doesn't even do with a try-catch...). The thing is that the ones that work are called with simply types, and the ones that crash have a type/class/structure in it.The documentation states how to call with "Visual Basic" without stating version. Here's how it looks..[code]I did figure out to use "Integer" in stead of "Long" and the strings needed some work but are fine now.Now... The "Type" doesn't exist in VB.NET so what should I do. Tried a class but that didn't work.I can call the DLL with "bad" data and get a good reply, eg "this and that is wrong with the input", but when I set that straight it crashes. I suspect that it's when it starts to write in the memory allocated by me and that does not match what the DLL expect.
BTW when I look at the class I made, I can see that - at least VS - lists the members in an alfabetical order. Is that how it's arranged in memory and could that be the problem if the order is different from the one expected by the DLL. I would epect that the total size was the same irrespective of order, so the problem would arise when I try to read the data and I would get junk.

I've got some functions I need to call that are in some DLL files that have been written in Delphi 5 in a VB.NET 2005 application. I'm able to use the DllImport function to access the functions just fine; however, I'm having an issue with the Delphi string data type and passing it to and from the .NET application.
[Code]...
It takes two string parameters and one double. I can call this function from VB.NET just fine, but it will error as soon as it tries to use one of the string variables (so in this case, when it passes them to another function) and I've found that the string values in Delphi are junk when they've been passed to .NET. I'm guessing that the string objects behave and/or are encoded differently between .NET & Delphi 5, and that I have to apply some sort of Marshaling to the function parameters in .NET, but I've tried all of the different types of marshaling and nothing has worked. Unfortunately, I haven't been able to find anything about this issue on the internet.
Does anyone know how I can call this Delphi function from .NET and have it pass the string values in a manner so that they won't be corrupted when stored in Delphi?
I have a Delphi written DLL that exposes some interfaces to a vb.net application.
The interfaces inherit from IUnknown (but this could be changed if required), simplified example:
IWindow = interface(IUnknown)
['{E9A11D0B-8A05-4CBA-83FA-C5CC6818DF6E}']
function GetCaption(var Caption: PChar): HRESULT; stdcall;
end;
[Code]....
Now I want to transfer a collection of IWindow to vb.net, and in the vb.net application I want to be able to loop through it with a for in loop.
I read that it's possible using IEnumerable/IEnumerator but I don't quite understand how to implement them. Are there any good tutorials about this, specifically showing the declarations on both side? Example code would be great.
Please note that I prefer not create a com dll that should be registered and imported. Currently I export a function that enabled me to obtain an interface.
I have a Delphi program that communicates with a vb.net dll that I created. The vb.net dll communicates with a Fluke scope meter via an RS232 connection. I have created a program that communicates correctly via RS232, giving me the anticipated value. Though, when I package this up as a dll and access the dll from my Delphi program I always receive a value of "1", rather than the value I was expecting (most cases a value in and around 240).I know that my delphi program is definitely communicating correctly with the dll and that my dll is definitely communicating with the scope meter
