Forms :: Create A List Of Records Then To View That Record
Feb 26, 2010
I have been playing with VB6 for quite a few years now and I can normally get by ok on my own.I finally made the move to VB.net, but I am totally lost.I have started writing a program that is basically a planner. It helps the user organize and plan activities with a client.I have created the ui and have added a BindingNavigator and it happily pulls in the records from my Access database which I can cycle through.What I would like it to be able to do is, allow the user to see all the current records (maybe in a flexgrid), select which record he/she would like to view, then the entire record is populated into the ui.I would have no problem in vb6 of course...but I could do with a little help in vb.net (2008).My main problem is I think is, once the flexgrid is populated, how to create the event that allows the user to view and update that record once in the ui.

how can i add records from list view to database ex. im going to have a transaction i will add products as many as i ordered in my listview and then i insert it into my database with the 1 transaction number it should be like this:
I have a datagridview with transaction bindingsource I want the datagrid to show the sorted rows only not all the records when i enter a value into a textbox and click button sort.
The ContextMenuStrip tied to the ListView control. However, the right click option (edit)appear where ever i click on the ListView area, this gives me exceptional error because the implementation of edit can only cope with a selected row. I only want it to appear when on a selected row (blue highlighted row). How can i do it?
I am essentially trying to create a list of records in VB.net using the 1.1 framework.It seems that I should be using an object even though I have only properties but no methods (more like a traditional record), I would like to store a list of objects, how can I create the list and add an instance of the object to the list.I do have sample code that almost works but it is too poor for public display.
I was wondering if there is any advantage to do everything programmatically instead of using design view to create forms, controls etc. Would there be any difference in size and/or performance after you compile it? So far I've been doing pretty much everything programmatically, specifying all the properties that aren't default for my forms controls but I am starting to wonder is there are any advantages to this, apart from making it easier (sometime) to manage and change the behavior of my controls.
I get some very generik trouble need to implement List View with Image in SubItem. All can be very fine ....But I need to use Virtual Mode. Whatever I search I haven't still found working solution's. I have found some C# code that seem's do that. But I can't convert it in VB.Net. let's explain detaly.
I am relatively new to C# and winforms, although I have been using Java for years, so forgive me if im asking something relatively straightforward!I have a DataGridView, it needs to update regularly so I wish to provide a Collection of objects as its DataSource and NOT a database table.So far I have a List<MyObject> which will be constantly updated via a BackgroundWorker thread. I want my DataGridView to update when a change has been made to the List i.e. if the objects are resorted, added to or deleted from etc.Currently my DataGridView only displays the first object I add to the List, if I add more the DataGridView doesn't update to display the new objects added.This is a basic overview of how im coding it:
private List<MyObject> myList= new List<MyObject>(); myDataGridView.DataSource = myList; Then my BackgroundWorker thread updates the list, e.g.
how to create a list shown in following image using vb 2005 ?i want the following list (contents doesn't matters) to be appeared when i click the button.
Basically, I am making a booking system. On one of the forms, you can: Add, Edit and Delete a record by using the selected index. I can do the Add and Edit part fine but some problems are occuring when I try to delete it. What I'm trying to do when deleting is, copy all the records except the selected one and then copy it back into the original file again.
I have a problem with my program, and it's really bad because I need to burn it to disk within 12 hours and I can't get it to work: If I create a record, add information to it and click on Next Record, the ID, Status and Notes boxes content will change but the rest of the controls contents are carried over to the next record and I don't know why or how. It was working perfectly but now it stopped and I never done anything.
Basically i am making a software that will be interacting with a database (sql).Now what i wanted is a loop which after every 30 minutes, connects to the database finds some info and executes a bunch of statements.For the sake of testing i have made the timer tick at 1 second, and display a record in a database in a label continuously just to see if it works (i will later make the tick 30 min)Now this is what i have tried till now , it prints the record in database perfectly after 5 seconds, but after that just fails.[code]I want to infinitely make a loop in which after every 30 minutes has passed it would connect to the database get a record and then use the value of that record to perform some operations. And this has to be done in the background.
i have use below code to make sure the listview only contain 3 record n if more than 3 records to prompt error message and disable the NEXT TRANSACTION button. it works well. But the problem is when i delete 1 record out of 3 it suppose enable the NEXT TRANSACTION button but the button is still disable. whats wrong with my code.
I have a whole bunch of duplicate records in my table. Using select Statement I want to display those records. the table name is Labs1 The 3 columns are:
I am loading a series of JPG images into an image list then using that to fill a list view. My program is using ALOT of memory by doing this. What would be the easiest way to add the images but take up less memory/time?
If I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.
#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?
i have a sql table which has 2 fields number & name
1 abc 2 xyz
Situation is that the app finds out max of number and increments it by 1 to get new number.The problem is when two users enter some record sometimes two records get saved on same number.
I am writing a programme that copies the selected row in one datagridview to a new row in a second datagridview when a button is clicked. the best way to go about this? This is my code thus far:
there are two computer connect to one shared database one of the user (user1) will insert new record then the records in (datagridview) of the user (user1) who insert the record will be 11 record but the(datagridview) of other user (user2) will still have 10 record.what the possible way that may allow me to refresh the records..Also how I can make a new record in datagridview of the user2 can be colored by yellow or red back color.
I want to display all records from database in gridview when pageload and also i wanna search for particular record using textbox appear in my webform...Means by default all records from the table will appear in gridview using sqldatasource and i also wanna search for a particular record by enter ID in text box...
