I started learning VB about one month ago and I try to make some programs to learn a bit. Right now I'm trying to make an application that will open a website, click on the url there, wait for a set amount of time, click on a button on that page then go back to the main page and restart with another url.

Is it possible to add the tips to your code in the sub so the user know what part of the sub is for? Like if I create a sub like this:
Private Sub Stuff(ByVal Tip as String)
End Sub
When the yellow box comes up you might see something like:
Quote:
Private Sub Stuff(Byval Tip as string)
This is just some text you use in the sub, don't worry about it.
I'm currently debugging a form that sets a flag when the mouse button is pressed, then clears the flag when the mouse button is released. As long as the mouse button is pressed, the user can move the mouse around and a few things happen depending on where they move. One of the things that happens is that a timer starts, or stops, and a few things change color depending on the mouse position. The timer starts when it should, then stops when it should, but once stopped, it is not re-starting when it should. I can verify that MouseMove events are getting through, because coloring changes as I move the mouse, as it should. This would be a simple thing to debug...except that it requires the darn mouse button to be down, and it uses the mouse move event. Anybody who has put a breakpoint in a mouse move event handler knows the issue: There are THOUSANDS of them. Worse yet, since the mouse button is necessary for switching to the IDE, as well as setting a breakpoint (technically, a keyboard shortcut could do this if I could shift focus), I can't wait for the problem to happen, then switch to the IDE and set a breakpoint to see what is happening then.Does anybody have any tips or techniques for debugging in mouse move events when the mouse button is down and has to stay that way? As it is, I'm going to have to write some funky code into the method just so that I have a place to get a breakpoint when I need it without breaking on every one of the mouse move events.

I've commented out various things to limit it to specifically this command (example, I can swap mklink out with notepad and it works fine). The command runs fine from a DOS window, but can't be found when I use it this way. I also tried using the SHELL command just to test and I get the same results. No idea why it can't be found, as like I said it executes from the command prompt just fine.
I've been programming in VB.net for a while now, and I finally got access to a mac to make ipod apps. What are some useful sites, videos, etc. that could help me get used to Objective C and the Xcode IDE? I've stumbled upon the samples on the apple dev site, but none of them really give good examples which I could learn the syntax of the language from.

View 4 RepliesI have made my application to start automaticly when windows start (registry ../currentversion/run/appname + path). In this mode the application start minimized and an little icon appear in the notification icon area. With this icon you can maximize the app or exit it.If you exit the app and start it again using the Menu (Start/programs etc) than the application start in minimized mode (and in this case I would like to have it in normal mode) because the setting autostart is still true.Is there a way you can detect when the application start when windows startup using the above registry or when people click on an icon in the programs menu (or desktop)?

View 4 RepliesInstead of the tool tips popping up next to the cursor, it would be more convenient for me to have them appear in a label on the status bar.
I've tried to myself, but had no luck. I also had no luck googling it. I mean, I could go about it in a shameful "ghetto rig" way by applying mouse overs to all the items and having them change the text in the label on the bar, but that's a waste of time.
The program should request the person's occupation, the amount of the bill, and the percentage tip as input and pass this information to a Sub procedure to display the person and the tip. Title is gratuities, first line Person's occupation, amount of the bill:, Percentage tip: Compute Tip, and show the tip. Im not sure how to approach it properly.[code]
View 2 RepliesJUst started to program in VB again after a long downtime (5-6 years).During this time I have been programing in ADA , Java and have therefore forgotten the "VB-way of doing things". Anyway..I'm triyng to build a web-aplication that looks like a normal questionform. [code]When the user hits "Submit" I want to add this information to a Excel-sheet(that exist in the same map as the web-page).Also I want to to program to check if that "Type" of event is already book for that date and time.I can easily do some of this in a "normal " application but is there anything special I have to think about when it's a web-app?Im also wondering how its works when you want to copy info from my application to a excel-book. How do I do that ?
View 2 RepliesI have a project with Control arrays that include over 200 controls.
I could use Tipster to define a Tool Tip or I could assign a Handler for the MouseHover event & use the handler to provide a help remark.
Would the Tipster approach result in the use of more memory/code than the MouseHover approach to this job?

View 11 Repliesworking with dates has always been a tricky part so let me show you how I handle dates in my application and please could you show how do you handle dates and also feel free to criticise. Normally I would create out a system to be able to save and then load a date note I am using a varchar(50) on my SQL Server db rather than datetime but I understand this is wrong, that's why I am looking for a decent way to work the dates out. My system has worked for me fine so far but if I would have to sort the dates ascending or descending I think I would get into trouble because it is saved as text.

I've made a download manager, which made out of several form.I have a problem with the first and second form, they are the mainly forms.The first is the main window. It contains the ListView, where you see the downloads, and buttons and etc.The second window is the window you insert the download link and press to download the file.I made everything, but when you press on the start button in the second window, it closes (as I wrote it to) and doesn't start the download.To check if it starts or not, I made a timer, which starts when the download begins, and it should show the seconds in a cell on the chart.It doesn't start it.I used this two lines to start download (the are in the button1_click in the second window):
Form1.download = New WebClient
Form1.download.DownloadFileAsync(New Uri(TextBox1.Text), Options.TextBox1.Text + "" + "123.exe")
Download is a public event and webclient.
Textbox1 is where the link is (direct link - if you put it in the adress in the browser, it starts downloading the file). Options.Texbox1 is the path (another window)The code of showing it in the listview is:
Form1.listview.Items(Counter).SubItems.Add(e.ProgressPercentage + " %")
Counter is an Integer that raise in 1 every click in the second form (to be able to make another row, for multiple downloads.
I am creating an application that is actually 4 seperate executables - UI is one and then 3 background services (console apps - no FORM's).I believe I can do one solution with 4 projects - would that be the recommended method? If a transmission class is common to all 4 would I make that a separate project or put it in one project and share that folder with the others? Can I have all 4 projects START when you click RUN?Does the OUTPUT window and other debug windows work with all 4 projects?Or is it better to make them 4 solutions for debugging purposes?
