VS 2010 Compile On WIN7 64bit

Aug 19, 2010

I'm using 2010 express, where can I find the compiler option for 64bit? or, it will compile for 32bit only? or, it should work for both 32 and 64 bit in most case?I'm using a 64bit component in the program, vb express reports error when I compile it, but if I use the 32bit compnent, then it is ok.does it mean express 2010 automatically compile to 32bit? or somewhere I should set the win7 64bit (which is what i'm using).just start using win7 64bit & vb express 2010, got confused

VS 2010 Strange 64bit Vs 32bit With Process.Start?

Oct 13, 2010

I am trying to execute DiskShadow on Server 2008 R2 via Process.Start


Now, what's happening is that the Diskshadow script fails with a "com call "(*vssobject)->initializeforbackup" failed." If I then open a command prompt/powershell prompt as administrator and execute "Diskshadow -s diskshadow.txt" manually it works just fine.

If, however, I try c:windowssyswow64Diskshadow -s diskshadow.txt I get the exact same error as when I try to run it via Process.StartSo, there seems to be some 32bit weirdness going on here when I try to run Diskshadow via Process.Start (Even though I am forcing it to use the copy in C:windowssystem32

How To Talk To A Modem

Jan 26, 2009

I'm a novice and after toying with some basic ideas on how to talk to a modem with, I think there may be much more to it than I realize. (?) I know my modem is fine, I can use hyperterminal to call out on it with no problem.So, how involved is it to talk to a modem? My initial thinking was that I could simply talk to it via a serial port using AT commands sent and rcvd as a string.(?)My modem is set up with COM2 9600 8n1.I've setup a serial port with the same parameters in my code.

Create A 2 Applications That Can Talk To Each Other?

Feb 17, 2012

Im needing to create a 2 applications that can talk to each other. One wil run on a server as the server application and others will run on workstations as clients. I want them to connect to the server app much like a chat program would work. I want to be able to send commands from the server to the workstations such as reboot, open this file, things like that. I also would like to be able to send the commands backwards to the server if needed as well. i think a chat program could be modified to do this by "watching" the message and if the word "reboot" comes through then the server/workstation would convert that to a command.

Make Two Applications Talk To Each Other?

Jan 18, 2010

I use several different applications for analysis of pupil data. Each of these applications require similar or identical data but because they don't draw their information from the same sources there is often a need to enter this data more than once which obviously is a waste of time. Some of the data is accessed through the intranet via IE, other applications are standard Windows apps. I would like to create some sort of bridging application to allow data to be automatically shifted from one location to another but have no idea how to use one application to control another

With regard to getting data from the intranet, I have managed to write an application that can retrieve some (but not all) data off a particular page of HTML. It does this by searching the source HTML but some of the data that appears on the page isn't present in the source file. This is very frustrating because I can see it in the browser but can't seem to access it through my application.

VS 2008 VB Apps Talk To Each Other?

Aug 22, 2009

What I want to produce is a form with about 20 text box's on it that are linked to a timer. That is easy, what isn't easy for me is how to get the data in a loaded form from access to another VB app. (timer form will be limited to one instance)

I have an access database which copies a string to clipboard and then opens a vb app. I have a button on that app which captures the clipboard text and moves it to an empty field starting a timer (lots of fields, keeps searching till it finds an empty field).What I want to know is: can access talk to a vb form that is already loaded and start a function?ORIf access can't talk directly to a vb app, can vb apps talk to each other and swap data (not just keystroke macros eithre)?

I can get access to copy text to the clipboard, launch a VB program that grabs the text in the clipboard and starts a timer, but can I get that VB app to talk to a second application?EDIT: I should add that VB doesn't need to talk to any tables in access, just what is in the clipboard.

EDIT: Tried to make 2 instances of the same app talk to each other using my.settings but it didn't work.
Could I make them talk to each other through a file other than my.settings file OR make the my.settings file absolute regardless of how many instances?

Program To Talk To A Network Switch?

Dec 21, 2011

I am not new to programming but have little experience and am trying to learn VB 2010.
We have HP Procurve network switches and I know that with a telnet application I can login to the switch and it will tell me which MAC address is connected to which switch port. Im trying to write a computer inventory program to track my computers and it would be really cool if I could figure out how to determine which computer is plugged into which port on the switch. Problem is that I have no idea how to go about doing that.

Is this anything anyone has tried before or does anyone know how to go about doing it?
Ive been hunting on line but havent found anything useful so far and thought Id ask here in the off chance someone knows what Im talking about.

.Net 2010 API To Hide Non Plug And Play Devices In Device Manager?

Feb 25, 2012

I'm writing a Windows Forms application in VB.Net 2010.  The application's purpose is to recreate the Device Manager in VB.Net.  The idea here is to capture the information provided by Device Manager and store it in a database.In turn this information could be used as a configuration management tool.My device tree is coming along nicely, with one minor exception.  There are hidden devices that Device Manager does not display by default.  Show Hidden Devices causes Device Manager to display these devices.  My Device Manager displays them by default.  I want to duplicate the Device Manager behavior of being able to hide and display these devices in my appilcation. I have had some success with this task in that I am able to hide the Plug and Play devices that are marked as hidden by windows by use of the "Don't Display In DM" flag.  There is the small issue of the Non Plug and Play Device Class. Is there a similar flag for Non Plug and Play devices? 

I have found a reference to the PNP_DEVICE_STATE and IRP_MN_QUERY_PNP_DEVICE_STATE IRP.It contains a flag PNP_DEVICE_DONT_DISPLAY_IN_UI.My problem is that I cannot find any guidance as to the structure of this API declare and the coding needed to use it.  I'm not even sure if this API will be helpful in accomplishing my task.I want to hide the Non Plug and Play devices and device class in my tree.I am using Visual Studio 2010 Ultimate and Running Windows 7 Ultimate with all Service Packs and updates applied.

Note "comstring" grabs my com port the serial device is using - on this computer it is com4, it is a public string

Why Will This Run In 32bit, But Not 64bit

Jan 18, 2010

I'm using the following code to iterate through and find windows containing specific strings in their title bars. I have two projects containing this identical information, yet for some reason - it works when targeted to x64, but FindWindowLike returns 0 always on x86. I need this to run in x86.I am developing this on Windows 7 x64, but it needs to run on my machine as well as XPx32. What I can't fathom is why it compiles/runs on x64 but not x32 (considering I'm targetting user*32*.dll)

Depending on what component is handling the print for you, some of them are not 64 bit ready (i.e. 32 bit only). To use them you must compile your application as 32 bit only. It will then run on the WOW platform that Win7 supplies.

You change this option on the PropertiesCompile screen. Press Advanced Compile Options and review Target CPU:

IDE :: Debug Not Working In 64bit?

Oct 12, 2011

I've downloaded the 64bit debug symbols and told the IDE where they were located. But for some reason, VS won't build a 64bit debug EXE.

This is my first time doing 64bit so I never had to worry about it before. Is there something I need to do in the IDE that I don't know about? I went to Project Properties and set things to 64bit debug. But when I compile the program, it makes a 32bit program.
