I am trying to make a application that will bind User Desired Keys to User Desired Text. This is what I have done so far, it is not very much but it keeps crashing and visual basic is not telling me anything is wrong with it. I basically just want the user to be able to select a hotkey from a combobox. [code]

i got the following things:
-A button (called "btnplayvoice")
-A textbox(multi-line enabled, called "txtinput")
-Some *.wav audio files in my "resources" (2 of them called "A.wav" and "B.wav", of course there are still some more sound files in my resources xD)Note: the button and the txtbox are in the same form.
i want to make a program with this feature:When I type "B A"(note between "B" and "A" has a space)into txtinput, then i click the btnplayvoice, it will look up and check the resources and see if the wav file exists there, if yes, it will play the related(same as inputed) sound files one by one in correct order. That mean in this case I should hear "B.wav -> A.wav" in this order.
I'm completely new to Visual Basic, so please be 'gentle' with me.I came up with an idea of a simple app (apps), which is almost done. I'm using Visual Basic Studio Express 2010.What I want to do is (well partially done already):One app (Windows Forms Application) launches another app. I'm using Shell command to start the other one.The other one is located on a network drive, but opens fine. The problem is that the another one (the second one) supposed to start a BATCH file (*.bat) in the same folder where the app is located, but it seems to be running in the same folder where the first app is located.In other words. App1 is C:my appmyprogram1.exe it starts App2 which is on a network drive, i.e.\mynetworkmynetwork foldermy program2.exe. Then 'myprogram2.exe' starts (suppose to) a batch file in the same folder \mynetworkmynetworkfolder, but instead it is trying to look for it in C:myapp . How do I tell the program2.exe to search for the batch file in the same folder where its located?
View 3 RepliesI'm automating a download,and I know the URL to the download page. Well, not exactly. This URL is indeed what I need to use, but the website redirects it to the REAL download page. Unfortunately the redirect only happens if I do an exit sub. That is to say, if I do a loop sleeping one second per iteration, the loop goes on forever waiting for the redirect. But if I branch out of the loop by inserting an Exit Sub in break mode, I can see the redirect occur onscreen. (I can watch the current page in the web browser transition to the desired download page). The trouble of course is that I don't WANT to do an Exit Sub at that point, so what's the solution? Do I need to call Browser.Navigate on a background thread?
View 4 RepliesI want to use webbrowser to go to a web site. This web site has three possible screens that I can get when I try to visit:
(1) A fresh login page, where it does not seem to know me and asks my name and password
(2) The main page of the site, with me logged in from my last visit
(3) A screen that says something like: "Thanks for visiting and logging out. click here to log back in."
I want to make it so that the webbrowser 1 ALWAYS is able to get to the first kind of page. When I have webbrowser1 navigate to the specified URL I want it to *not* be redirected to already being logged in from last time and to *not* be redirected to the third kind of page.
I am trying to make a program so that it goes to the site, enters my username and password, and clicks the "login" button. This is getting messed up because it does not always go to the first kind of page, and, actually, most often redirects to the second or third screens, to my aggravation!
Is there some command I can use with webbrowser and my visual basic 10 program to make it so the webbrowser is NOT redirected without me wanting it to be, so that it always goes into the "fresh" login page?

View 15 RepliesTDD is supposed to have 100% code coverage. Does this mean one is supposed to write tests for property getter and setters, and other methods that contain no real logic, such as dealing with external API functionality? Below is one example method (which happens to also be the example in this other SO question which deals with how best to test it, if we are going to test it). This method doesn't do much. It's a facade of theSystem.ServiceProcess.ServiceController functionality of stopping a service. Currently this code was not being written using TDD, but if it was, would it be something that one should test? There is very little logic here.est to test it (IoC & Adapter Pattern vs. Detouring) please see this other SO question.

I am using the following Caml Query to get data from a share point list.
oSb.Append(" <OrderBy>")

But this query is giving me all columns of list. Is there any way to get only desired column from a share point list using Caml Query?
In my project, it is desirable to access built-in color, dash styles, hatch styles by a numerical index rather than their names. For example, I would like to access the colors in a loop from 0 to 140 and display each of these in side by side rectangles in a picture box. Then later, when I click on the rectangle for a desired color, calculate the index of the color from the position of the rectangle in the picture box and use this index to set another object to the clicked color. I understand the coding for all of this except for how to get the colors from the enumeration in the loop and later, after I get the index from the clicked picture box, how to I access the desired color from the enumeration by using the index obtained from clicking the picture box.
View 5 RepliesI created an exe app in vb.net and I want it to run every 3AM so I used the scheduled task feature of Windows 7. The app has an initial form that will countdown from ten before proceed to the main process. My problem is that the form doesn't poped up. But when I look at the task manager, my app is running. I don't know what's wrong with it because when I tested the app to run at times when I am viewing it, the initial form pops up. I already set everything like to Run whether user is logged on or not. So I really don't know what wrong with my app.

im trying to make a program that only listens to a few keys that the user presses, and if one of them is pressed, it carries out a specified command.for example, right now,i found a keylogger that could carry out my command, but id rather use something else if possible. right now, i have a timer running this:
For i = 1 To 255
result = 0
result = GetAsyncKeyState(i)[code]....
Then, in the textbox1_textchanged, i search for like if textbox1.text.contains("M") or something.problem with this, is im pretty sure its a keylogger, and i dont want to have to have that. also, it does not work in vista.
Found a solution! (should have researched more throughly!)

The "named pipe" seems rediculous to pass data between processes (exe's). Is it possible to run a single instance of a VB.NET Class Libary (dll) such that two programs can access the same memory resident dll, thereby passing data via functions and or subs?When I try to make the class library as single instance, the "Enable Application Framework" is greyed out, and thus the option to "Make Application Single Instance" is also greyed out.When I try to call the dll from two processes, I simply just create two instances, so storing data in a module doesn't work

View 8 RepliesI have finished coding a VB.Net application that has connection to SQL Express 2008 database. My question is, what steps do I have to take to make this a multi user application.
FYI:There are 3 tables in the database of which two tables contain data to be viewed by the user and one table is to insert records by the user. The former two tables will be edited by the administrator only. So there is no issue of concurrency. But the one table that is used to insert records by all users has to be dealt with.

View 6 RepliesI am designing a fairly small application to manage a waiting area for a clinical department. There will be a receptionist who books appointments and updates exisiting appointments to say that a patient has "Arrived". In seperate rooms will be nurses who call patients who have "Arrived" and update the appointment as "In Session" and finally as "Discharged". The appointments are viewed in a flexgrid with nurses across the top and time down the left, patient names are displayed at the relevant times and the cells are shaded a colour to represent the current appointment status ("Booked", "Arrived", "In Session" and "Discharged").
I am using SQL Server as the back-end and Visual Basic 6 (I know) as my front-end.I have been told that there will be 2 or 3 nurses plus the receptionist logged in to the system but I would like to cater for growth.My question is what is the best mechanism to use in order to reflect the status change made by one user on the screens of the other users currently logged in?
I have been thinking about using a timer to refresh the data at a set interval but I do not want to keep hitting the server excessively (although what is considered excessive? we would be talking about a call for data every 60 secs per user). Plus the server could be serving data for many other applications so this is another consideration.Alternatively I have been thinking about sending some kind of message via Winsock to the other users notifying them of data changes as they happen. I don't have a lot of experience with this and am concerned about clients not receiving messages and users seeing old data. It also seems strange to me that once the days appointments have been retrieved from the database that "in theory" a client could go the whole day without having to query the database again to pick up changes - kind of scary.Some information on the data:We would probably be looking at around 100 appointments per day We capture patient name, date of birth, date and time of appointment and appointment status.What is the standard approach / best practice for this kind of scenario?

I'm running an application under an account that is not the account logged-on to the PC.
Within the application I need check if the logged-on user is a member of the Administrators group. Below is the code I'm using. From what I've read, WindowsIdentity.GetCurrent() should return an object associated with the logged-on user. It doesn't, it returns the same information as the call to System.Threading.Thread.CurrentPrincipal. Which is the information associated to the ID running the application, not the logged-on user.
