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 13 RepliesThe extent of my experience with SQL server is simply adding a database to my current windows application and then performing queries through the interface I created. Everything is fine but I want to move to the R2 version to allow for a 10GB limit.I have downloaded the new version and successfully ran the install. But, I am at a complete loss now what? I know this is probably ignorant, but what is the next step to making sure that the database currently set up in my application will now utilize R2?

I need some advice to make a small application running, i need to calculate a integer prime and i use a recursive function inside a while true loop, first i get a random number with random class and then i call the recursive function that checks if it's prime, if it's prime it exits the while. Sometimes it works others throws the stack overflow exception, what i must do to get rid off this exception?
View 4 RepliesIs 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 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.

I want to add Tool Tips to a the controls in a ToolStrip. I add a Tool Strips control to the form and there is no property for it, only for the generic Tool Tip which doesn't have the same features.
View 9 RepliesCan you guys share some techniques and methods on how you validate dates, where and how to do and stuff like that.Like If you were to set a new employee's five month contract, and having him/her account terminated on contract ending.Let's say I built a Lan-Based Management Information System and a small application that will automatically routes/scan every dates in the database every 1 mili-second using a Timer Control in VB to identify which date has been reached to dismissal phase.
View 4 RepliesI'm about to start a new project, its a Payroll System, I'll be using VS 2008 and my dbase is MS SQL Server 2k5.I just want have some tips for this kind of project.
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?
I got an email I just created using Outlook automation and I need some help to get it formated nicely:set Font of the body set font-style to bold of certain words insert a picture into the body (this is not an attachment) when putting text in the body using VB.net looks like outlook automatically adds spaces for each "paragraph", how can I get rid of these spaces? how can I get my signature on because it disappears when text is added to the body [Code]
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 have set up a method in vb.net and in xcode for encrypting a string using as far as i can tell the same parameters for an AES encryption.I've looked all over the place but cannot find information on whether they use the same encryption algorithm and settings.
this is the vb.net code:
Dim encryptAES As New AesCryptoServiceProvider()
Dim encoding As New UTF8Encoding()
Dim encryptor As ICryptoTransform
encryptAES.Key = encoding.GetBytes("12345678901234567890123456789032")
encryptAES.IV = encoding.GetBytes("1234567890123416")
encryptAES.Mode = CipherMode.CBC

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.
