hi,
i got the solution for open the open office document.
this below coding not only open open office document . we can run any application through this coding ....
Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" ( _
ByVal hwnd As Long, _
ByVal lpOperation As String, _
ByVal lpFile As String, _
ByVal lpParameters As String, _
ByVal lpDirectory As String, _
ByVal nShowCmd As Long) As Long
Private Const SW_HIDE As Long = 0
Private Const SW_SHOWNORMAL As Long = 1
Private Const SW_SHOWMAXIMIZED As Long = 3
Private Const SW_SHOWMINIMIZED As Long = 2
Private Sub Command1_Click()
ShellExecute Me.hwnd, "open", "C:\pdf\v.pdf", vbNullString, "D:\", SW_SHOWNORMAL
End Sub

I have a VB.NET program that calls a web service (using HTTP GET). The web service returns two types of files, with different file extensions: .PRD and PRD.OLD). How can I make the VB program check for the presence of either one of the file extensions? I mean: sometimes I need the .PRD files, sometimes I need a .PRD.OLD file). Currently, the VB.NET program will download everything from the web service, and that is not what I want.
I have used the following code:
Dim Request As HttpWebRequest
Dim Response As HttpWebResponse = Nothing
Dim Reader As StreamReader
Dim Result As String
Dim xd As New MSXML2.DOMDocument30
Request = DirectCast(WebRequest.Create(Address), HttpWebRequest)
Response = DirectCast(Request.GetResponse(), HttpWebResponse)
Request.Method = "GET"
Request.ContentType = "application/x-www-form-urlencoded"
Reader = New StreamReader(Response.GetResponseStream)
Dox Girl, where are you?

Depending of what this service gives you different types of files?
|

How you do this depends entirely on what you get back from the web service. If the service just sends you a stream of bytes with the file contents, there's no way tell what the filename is. If the service sends you back a structure with the filename data, great! You've got what you need.

Friends,
I am Shailesh. I work as a MS VB application programmer. MSCOMM control is used to acquire data from COMM & USB ports. These application programs ordinarily run on (thick) PCs where data is to be acquired and processed.
Recently, one of the clients decided to move away from PCs to HP Thin Clients (TC) T5500. I have been asked to prove the concept i.e. to acquire data on a COMM port on TC.
I have made a set up with Windows NT server (Server 2003) & HP TC t5500. I have built a test program to acquire data from COMM port. This program (of course) runs fine on the server, acquiring data from server COMM port.
I have connected TC in the LAN and ran a RDP from HP TC. The program runs but it acquires data from server COMM port rather than TC COMM port. I have also noticed that if a COMM utility like Hyper terminal is run in RDP, data is acquired from TC COMM port and displayed in Hyper terminal.
This would mean data is transferred from TC serial port thro’ TCP/IP to Server.
Question –
1. How do I acquire data from serial port in a VB program in this set up?
2. I will also like to receive inputs for this set up and get this set up working.
3. Eventually up to 50 TC will be connected on the server. Server hardware will be high end to handle large number of TCs.
4. I have been also told that Citrix or VMware can be used to read data from remote serial port ?
I will sincerely like to receive your inputs.
Thank you in advance. Regards.

That depends on where your code is running. If it's running on the server, then it has no access to the COM ports on the clients connected to it. You'd need to write a component that runs on the TCs and handles COM communication and transfers that data to the server. The server would not be using the MSCOMM library at all, the clients would.
You cannot use Citrix or VMWare to do this, since both solutions would still be looking at the COM port on the server, not the clients.

Dear Dev,
Tks very much. I still have a query.
The program runs on the server, client is used almost as a dumb terminal but COMM ports are to be used. As mentioned in my first posting, after running RDP from the TC, serial data from TC port is displayed on a hyper terminal running on TC (Pls note RDP on). Does this not mean data from TC COMM port available to be read by Server ? If affermative, we can explore further possibilities.
Once again tks. Shailesh

I take it, by RDP, you mean Remote Desktop? Is the server controlling the desktop of the thin client or the other way around??
sachin2 2010 wrote: after running RDP from the TC, serial data from TC port is displayed on a hyper terminal running on TC
So, you running HyperTerminal on the thin client machine and seeing the data that's on the thin client?? Obviously, this would work since they're both on the same machine.
sachin2 2010 wrote: Does this not mean data from TC COMM port available to be read by Server
To a point. The Remote Desktop software can expose the local serial ports to the machine being controlled, but only through the remote desktop software. RDP has its limitations, such as if a connection between machines is broken for some reason, you'll have to restart the RDP session. It won't recover by itself. All you're doing is adding a layer of complexity you don't need and you need.
If all you're doing is taking data from the serial port of each thin client and sending it to the server, you write an application that runs on each thin client and sends the data to whatever server software you have running on the server.

Dave,
Tks again.
RDP is Remote Desktop. Server is controlling the Thin clients.

Sachin 2010 now writes:
Since TC is connected to sever as RDP, when hyper terminal is run on TC, it is an application running on the server. Is my understanding correct ?
or the application is running on TC RAM etc ? If application is on server, how does program read data from TC server ?
Your point about session disconnection is noted. It is an irritant.

Yes sir, that is what I want to achieve (amongst other things). The problem is TC has no hard disk, USB port is disabled. Then where do I load VB exe for data acquision from TC serial port?
If there is any other way, I am more than receptive.
Tks again. Kind regards, Shailesh

No. HyperTerminal is running on the TC. A RDP session remote controls the target machine as if the keyboard and monitor of the machine you were sitting at is connected to the remote machine. All applications you see running on running on the remote machine, not the local one.

The TC's can map a drive to a share on the server and get the apps to run from there.

I am inexperienced in VB and have developed a VB version of an old simple turn based game that I used to play on an Apple II 30 years ago. I want to include a capability to communicate between two instances of the application so that small, simple packets of data can be passed between them to allow for the turn's moves and results can be passed between the two instances. The two instances will be on separate networks so I envision internet communications to pass the data.
I have been using Visual Basic Express 2008 and have not been able to locate help or code samples to assist me.
Is this a capability not supported by VB Express 2008?
Is there reference material or examples that might be helpful?
Any help would be appreciated. Thanks in advance
Bubba...

Hello Everybody,
Actually i want to use my application to Full trust appliation. After a lot of searching i found some help from google. He says that Wintrust.dlll is used to perform this action.
So please help me how to use wintrust.dll to execute my application to Full Trust.
Thanks
If you can think then I Can.

The machine has to be told to trust the application. The best your app can do is to request FullTrust permissions. You cannot use wintrust.dll to force your code to run as "FullTrust". Telling the system to trust your code is normally done at installation time, not runtime. All code the user launches executes AS the user and cannot grant itself more permissions than it already has when launched.
Code can be run from various sources, either local, network, or whever. Each of these sources falls into several categories, called Zones, like MyComputer, LocalIntranet, Internet, Restricted, and Trusted. In a default configuration, if your code was installed on the local drive, it would be running from the MyComputer Zone and have more permissions to access machine resources than if the very same app was running from the LocalIntranet or Internet Zones.
I highly recommend reading up on Code Access Security so yuo understand what's going on and how to apply it to what you really want to accomplish. BTW: You never said why you want to do this.

Assuming that you're referring to the local file-permissions;
SetAttr("C:\boom.bmp", vbReadOnly)
Giving rights to a specific user/group from the Active Directory is somewhat more work.

Hi,
I have with cp help and some other sites added t2s into my program. Unfortunately the only speech installed on the systems is Microsoft Sam. I want some others preferably Dutch and French. Someone has an idée where I can find them? (And yes I have look into Google but find nothing useful)
