I have VB project and I tried to use PUBLISH feature.It seems to create nicely some kind of setup program, but the setup program does not ask where to copy files (it does not seem to copy filesto target machine "PROGRAM FILES".)Is this setup program somehow different from usual installers?

I am trying to retrieve file details from files in the Program Files folder. I receive an error while trying to retrieve file details.
Dim sFileName As String = ("%ProgramFiles%Windows DefenderMSASCui.exe")
Dim Info As FileVersionInfo
Info = FileVersionInfo.GetVersionInfo(sFileName)
Msgbox(Info.ProductName.ToString())
I receive file not found error at 3rd line. But if I change the path from "%ProgramFiles%Windows DefenderMSASCui.exe" to "c:Program FilesWindows DefenderMSASCui.exe" it works fine.
What should I do if I want to retrieve file details from the path which includes a "%" character?
Having a slight permission problem with Win 7 I am guessing it will be the same on Vista but work fine on XP (yet to try)But my program is sitting in: C:Program FilesCompanyProgram And its trying to create new files alongside itself in the Program Files area but bombing out which I know is permissions. If I go there to create the file myself it comes up with a UAC prompt and when I hit allow it works fine but obv the program can't do that byiteslf so bombs out.Is there anyway I can over come that without the user having to grant admin rights to the program each time it starts or do I have to write data to another place?
View 4 RepliesI wrote a program to download and play AVI files the files are large in size and long time wise. I have the files playing as they are being downloaded but i can't see how long the file is or seek reliably. i was reading that the AVI headers are in the last 512kb of the AVI file *why would't they put it at the start* lol so my question is is there a way to download the last 512Kb of the file i'm downloading. i have the Bytes Read and Length of the file while its downlaoding i'm just not sure where to go from there, or how to do it atleast. If i had the length in time of the Avi file i could set the trackbar to be able to seek properly. or if someone has an idea how i could get the time of the video by using fps and some math i could prob do it that way too but idk how i would tell how i can find how many kb are in the fps i'm sure it changes so think that way is't going to be reliable. how to get the last 512kb would be the best option not sure if it can be done even.
View 4 RepliesIn class i saved my program in with load of other test programs for the same assignment and got everything mixed up i finally figured out what was what and loaded the program in Visual Basic. Now my program doesn't recognize one of my forms when i try to access the design view of it. I hit run for the hell of it and the program runs with errors of course but the form1 "the missing one" shows up with all the buttons etc and i can use it.

I have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.
Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?
Here's an example of what I would do:
Hex = 03 00 => dex number 003
Search in file Pokemon Dex Numbers
003 returns Bulbasaur
Check Bulbasaur base stats in the base stats file
etc
So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).
So to cap up the few questions I have:
-Databases are done in SQL and not inside the GUI?
-Databases would load internally?
-I could search a database without having to load it into like an array or something?
Have a Windows app that needs to interact with a stand alone program that is accessed using cmd.exe. From Windows app, I can execute cmd.exe but cannot interact with it. Tried SendKeys, but this only sends one key at a time (sometimes more, but inconsistent) with multiple cmd.exe windows opening. Need to be able to send a whole command (string) to only one cmd.exe window.

View 2 Replieshow to display and interact with a website, at the moment its just research on how to go about it. Once i start i may need some more assistance. But for now just research At the moment Ive came up with using WebClient and HttpWebRequest/HttpWebResponse to interact with website data. And i know VB.net has an inbuilt site viewer (just a wrapper for IE).The website im using is an Intranet page for doing VOIP calls. It uses a large collection of JS(jQuerry) mostly. I can probably get the dev to make a .php file to
<?php
print_r($_GET); Prints all GET variables in a quite readable manner.
print_r($_POST); Prints all POST variables in a quite readable manner.
?>
to find out what GET's and POST's there are, but I'm not sure if JS stuff gets put in as a GET or a POST as its in the DOM.So all in all,I'm wanting to make a "Desktop" variant of there client. So basicly just a viewer of the dial pad. And detection of new calls in the queue, things like that. So i want to read data from the website, display the dialpad(just showing a segment of the website) and send the request to accept a call(and maybe a few other small pieces of data).
At user login, launch an app I have created. This app opens a web site in a webbrowser control, logs the user in to the web site, and parses links from the resulting web page. These links are links to launch citrix sessions on another farm.
Create another app that appears on the start menu for the logged in user. User clicks on this app, it communicates with the launch app to basically click the href associated with the citrix app within the webbrowser control. Then this app will go away...
I have already coded the first app and figured out how to click links within the webbrowser control. What I can't figure out is how to go about implementing the second app, that runs as a separate app, but communicates with the first app to do its business. I see a plethora of options such as MFC, AppDomains, RPC, and so on. My question is which is the best practice to have one app interact with another and have the other app take actions based on that interaction? I prefer to stick completely to vb.net.
A good example of how I would like this to work - a web browser (IE, FF, whatever) is open on the desktop, user clicks a link in an email, link opens in running browser. An action in the mail client causes action in the browser.
Im not understanding something or I am missing something.I can't use: "Imports Microsoft.Office.Interop" as it is not recognized.How do I interact with an Excel file? None of the examples I have viewed have been able to work.I opened one VBform (only the form) by ".paul." (in his sig) but could not get it to convert to 2010 and although I was able to get his code loaded I could not use any of it.The strange part is in his module there were no errors, import (copy and paste) any of it to my project and everything had errors.I believe .pauls.'s example was:"Imports excel=Microsoft. Office. Interop" which was not being accepted in my project.

I have never interacted with Varbiles outside of the projject but now in need of it.I am developing a Windows Service Application that is multi-threaded. There is going to be a set of Global Varibles in the application that contain basic status information such as how many threads are currently running, What clients are currently connected etc.
Now I would like to develop another application as a monitor. This one would be a Windows Forms App and its sole purpose is to display to the user this information so that is can be monitored.Is there an easy way of doing this? If not I don't think I will bother as the Monitor is not essential.
How can my VB.net application interact with windows modal dialog boxes?
For example when you click an HTML <input type=file> the dialog that opens is a windows form that isn't in my application, so how can I manipulate it?
My application needs to be a service (it needs run regardless of whether a user is logged on), but I also need some sort of client control/oversight over what it is doing. What is the optimal way to do this?Write a separate application to communicate with the service application - I see that as best solution in terms of stability, since the applications will be decoupled somewhat Use callbacks on system events in the service application to load UI forms directly from the service application - I see this as being easier to deploy.
View 2 RepliesSo I am currently using the method of combining a timer with a WebBrowser control to constantly check if some particular text has appeared in the WebBrowser control on my form. The text is dynamically generated after some arbitrary amount of time depending on the user's internet connection speed. (I'm using DOM to do this). The code to check for the HtmlElements lies within a function, which is turned called by the timer.
I find that this is kind of crappy and occasionally lags the UI interface, if not making the entire program behave sluggishly. I have been thinking of just using a simple while loop in a worker thread to take care of the issue, but I understand that new threads cannot interact with the UI thread directly (including controls); they have to call wrappers that are present within the UI thread.
So my question is, can you declare a WebBrowser control and still interact with its HTMLDocument properties if you declare it within a worker thread? I don't want the while loop to be executed within the UI thread (by using a wrapper), since that would defeat the purpose. I would also like to avoid DoEvents() as much as possible...unless that's the only way to do this thing?

I've search numerous hours, but I haven't been able to find the appropriate solution. What I want to do: Get the html of a certain webpage (Lets say in this case url...this html within my wpf application, so that you can see the content of the page you requested. Then I want to be able to trigger events on the html that has been loaded from the URL. Like I want you to be able to click on a certain node in the HTML and I want to be able to link this node to a certain value. Basically a crawler application that let's you request a page, see the page in a control and allows you to click in the loaded HTML and link values to predefined values you set. So basically I want to be able to get a webpage displayed within my application and be able to trigger events on the html (For example a click on the html which would need me to know on what node you clicked in the html, or for example be able to edit the html by clicking in it).

View 6 RepliesI'm trying to write an application in VB 2010 that will allow me to send out stop and start commands for two services. I can get this to work in a batch file but not in VB, using either NET STOP and NET START and also using SC.exe Stop and SC.exe Start. But I don't seem to get anywhere if I try to use this in VB. So far this is what I have written, using the Print Spooler service as an example. The two services I actually want to stop and restart are the Server and Client services for efpos terminals that are attached to the computers. The service fails from time to time and I want to provide a solution for our users that is quick and easy for them to use, and most importantly doesn't require them to restart the computer, while they have a line up of people waiting to pay.
Code:
Private Sub SpoolerStop()
' Stops the spooler service
Dim StopSpooler = "C:windowssystem32sc.exe stop spooler"
End Sub
No matter what search terms I try in Google I get very little on using VB to interact with Windows Services.
