OK So basically as the title says, in my browser i have tabs, now when a new tab is open and the user will go to a new page, if they click to the next tab the url box & document title remain the same (until they click a link or something) are there any methods of detecting when the person clicks to another tab so that i can code it to change the textbox and form text?

I have two combobox in a form: Cb1 and Cb2
When I load the form, Cb1 and Cb2 are connected to a bindingsource.
When I change Cb1, the code (below) changes Cb2 to show only the items according to Cb1
This is working fine.
The problem is when I change Cb1 , change Cb2 and click the save button..... Cb2 seems to be 'lost'...
I'm using VS2008.
CODE:
I have a DGV I am working on, and I have many columns.
For example I have Columns colcase(Combobox), colreportTime(Time)
the combox shows 4 cases {A,B,C,D}
what I need to do is if the user select "C"
the the colreporttime will show the time of this change unless the old value is C
I'm getting familiar now with using the Dataset Designer and how it makes for quick and easy updates and query of tables. I use to use the OleDB commands and leave the Connection String as a Global Constant so I can easily change it if the server name changes, or if we have to re-direct the .NET to another instance of the database.
But now that I use the Dataset designer I'm concerned that I maintain flexibility and support in the long run. how the Dataset designer works and where it stores it's connection string info? And how difficult that would be to update. It looks like I modify the App.config file, but I'm unfamiliar with this.
What am I getting myself into? It looks like a standard XML file. Is that it?
Ok, so I know I have to change the labeledit to true but that doesn't change the selected node to be able to edit, so how does that work?
Along with renaming I have it set to that a user can add a node. So once the node has ben added how do I let them rename it as it is being added and without being a prompt or inputbox? So lets say I cam clicked on a parent and they click add node, it adds it to parent but I have it so it is default "New" but I want them to edit it as it is added. I think it will be along the same lines as clicking on one and rename but I have to start some place.
Can someone please help me create a very very simplistic sample page as the chat page included is too coomplete. something as simple as detecting a change in the database and displaying the word "change" on screen in realtime for any client connected.and I tried creating a global.asax file into which I added in the line mentioned in the link above, but it does not seem to like the word "Setup" in the line [code]

I have 10 Comboboxes in a form. All these combo boxes have databound items which come from the same column in a table in the database (access 07) (Am designing a billing software, and these comboboxes show the items (10 lines of them).All these combos reside in one Groupbox.Now for the strange (scary/funny) part, whenever I change a value of 1 combo, all the other combos change automatically and show the same value as the one that was changed. (strange!).
View 6 RepliesI have a change calculator program that has two user inputs and 6 outputs. The user inputs how much money is owed, then how much money is received. IT will then display how much change you need to give back. It should also display the different types of currency that are available to give as change. Here is my code so far.

I'm working on a simple base form in which all the other forms in the project will inherit. This base form only adds 5 properties (at the moment) dealing with painting a gradient background. The problem I'm facing right now is when I change a property on Form1 (the test form) and click run it doesn't show that change. I also checked the .designer.vb file and when I make a change it's not added to the code behind file, I'm at a loss right now to why.

I am throwing some data out into Excel and am having some formatting troubles. I have 5 columns (date, time, a long number I don't want displayed in scientific notation - text is fine, text, text). I can get it all working with numberformat, however I have to do them different ways.
Date works this way cell.numberformat = "m/d/yy" and it formats it to say 3/1/11
Time works this way cell.numberformat = "h:mm AM/PM" and it formats it to say 8:07 AM
For the long number cell.numberformat = "@" and it doesn't change the format and it gets displayed in scientific notation
BUT if I use cell.style.numberformat = "@" it works as it should, but it messes up all of the date and time cells. Apparently when you use style.numberformat, it doesn't just apply to the cell you're working with. If I try using style.numberformat with the date and time formats, they don't change and are entered as if I didn't change the format at all.
So, I've got a text boxes which loads up a content from a XML file, usually a numbers I want a button, so when I will change the numbers on the text box, the data in file will change as well, in other words a save button That's how the data is being taken from a file

I have a large project that was originally written in VB6 using an ACCESS database. I want to rewrite it in vs2008 and change the database to SQL 2008. Someone on this site suggested that I look into NHibernate, which I am trying to do. Most of the samples are written in C#. My question is, does anyone know where I can find a sample of a project that is using NHibernate and VB.net? Or is there a better way to go?
View 1 RepliesI'm developing a Windows form. It contains textboxes, checkboxes and so on. When I move these controls (e.g. cut & paste from one frame to another in the same form), their names do not change (and it's good of course) but their function and event names are changed. Why it happens? How to avoid it? It causes me to move all functions from the old control to the new one. It's a lot of work and very annoying.

The reason I dont want to use the disable function/read only is because it puts the gray background on.
