Cmbprojtype To Be Displaying The Txtprojtype Value For That Record
Apr 29, 2010
I have a textbox called txtprojtype, which is populated on the form.
When a change details button is clicked the txtprojtype is visible set to false and it is replaced with cmbprojtype with a dropdownlist read from the database, incase the project type requires a change.
Now I want the cmbprojtype to be displaying the txtprojtype value for that record.
This does not work;
txtprojtype.text = cmbprojtype.text

I got 100+ textboxes that display record values. Most of the textboxes display correct values but several textboxes doesn't. These are the same textboxes. And they only display wrong values if I edit a record for the first time. After correcting the wrong values in the textboxes the first time, they display correct values in succeeding editing of records. Tried to compare their properties and all but they are the same with textboxes that worked...

While I've previously many years of relational databases and procedural languages, I'm stumbling with Visual Basic. In this problem, the simple situation is that I have two files, parent and child. The primary key of the parent file (Area file) is linked by a relation to one of the two fields that makes up the primary key in the child file (Project file) (unique key is formed from 'area' and 'project'). I have the default table adapters created on both files. I have created two maintenance forms showing one each of the two files in datagrid view format.I can create some records in the Parent (Area) file, but when I try to create a record in the child (Project) file, using one of the valid key values from the Area file, I get the 'ForeignKeyConstraint [relation name] requires the child key values [actual value] to exist in the parent table' which I'm absolutely definitely sure it does.
I haven't done any actual coding for those two maintenance forms, just dragged-and-dropped the files from the data sources screen onto separate forms so it creates the controls itself. But I can't work out, if it already knows the data does exist because I can load it back in to the Area maintence form, why it can't check itself to find out the record does exist. Why does it think the record from the parent record doesn't exist? It does exactly the same thing, whether or not the database is in access or SQL Server Express. I have all the latest updates.

I have two tables Products and Categories with a many to many relationship. I am trying to copy the categories linked to one product (OriginalProduct) to another product (newProduct). The problem is when I execute the SaveChanges() method, I not only get the records in my linking table, but it also creates another copy of the categories in the categories table. I've tried this in many ways but here are the last couple that I've attempted:
' Copy Product/Categories
For Each oneProdCategory In OriginalProduct.Categories
Dim relatedCategory = _productContext.GetObjectByKey(New EntityKey ("ProductInfoEntities.Categories", "RecordId", oneProdCategory.RecordId))

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.

I am handling many of the BindingNavigator tasks (MoveFirst, MoveNext, etc.)in code to ensure that I always ask the User to save his changes.
The one area I am have a problem is PositionItem. I would like to sense that the User has changed the Record Number in the BindingNavigatorPositionItem, handle my record Update, and move to the Record Number the User entered I have looked all over and have not found any way to do this.

I have created a project that has an add a new record, edit record and a search form, that has multiple text, combo boxes and is working great.Last nite I have added a checkbox under my add new record form and i am saving the checkbox value to my database, so far so good. I would like to be able to search any record that is mark with a checkbox to show up in my search screen when I do a search: [code] The problem that i am having is that now that I have added the code to my project to search for the checkbox field in the search screen and if I leave everything blank and click on the the search button I get no record found. I expected to see all that data, since I have nothing selected. Now if I click my checkbox, as soon as I click on my search button I see that two records that I have added for my test.

I'm receiving the following error:"You cannot add or change a record because a related record is required in table 'FORN_NIB'."
I cannot understand this error fr the related record really existe on the FORN_NIB table. It is even picked up from there. Here's the code where the error occurs at the .Update instruction:
HTML With rst

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.

Visual Studio Pro 2010 Win 7 64 bit running bootstrapped to a MacBook Pro i5 (blasphemer!!!) works really well though!!New to vb.net, have used vb6 for several years and finding the transition interesting to say the least.I have an access database with a vb.net front end all auto bound by the connection and binding wizards (I know, I know...) Not too complicated, but a simple 2 table related db. On the form the parent table shows customer details with the child table related and displayed by datagrid. I have a field in the child table for images and I have figured out how to store and retrieve images to the db. I am using the datagrid.rowheadermouseclick event to reload the picturebox on the main form as I click down the child table datagrid. Now I need to be able to click the bindingnavigator, go to the next record and have the program reload the image for the next child record. The problem is I'm trying to use an event from either the datagrid or bindingnavigator to reload the picturebox in the child table after moving to the next record, but all of the events I am trying are firing before the next record is moved to and therefor the logic I'm using to retrieve the image from the db is not working.
Anyone with an idea on how to move to the next record and then run my logic to populate the picturebox? What events might I use that fire after the next record has been populated? I know this is probably not that hard, but I have been racking my brain all day now.

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 now wasted over two days going round & round in circles with the pathetic excuse for a Help System Microsoft now makes us put up with (& nearly blown my monthly broadband data cap doing so).I have lost count of the links that do not exist.The Give Feedback option also does not work (I do not like Microsoft Outlook, & in spite of having set Windows Mail as the default mail that doesn't work either!).Every VB example I have downloaded has failed to operate as it should (if at all), so surprise, surprise nor does my implementation of what they say is how to do it! please give me the "exec summary" version of what I need, ON ONE PAGE which is: Correct way (& syntax) to (in VB code):
1 Open an existing SQL compact 3.5 database THAT IS WHERE I SPECIFY - NOT WHERE the wizards keep saying it is(it against my instructions)!
2 Search to see if a particular record exists in the database (eg WHERE ColumnName. FieldContents = ContentsImLookingFor)?
3 Retrieve the found record into my own record buffer?
3 Add the record if it does not exist?
4 Change the record?
5 Delete the record?
6 Close the database?
The rest I will do MY WAY, a thousand times faster & more efficiently than anything I've seen "documented" so far. Surely that is not a huge ask requiring GBs of "Help" garbage leading nowhere?I've only been programming for 25 years (but not in this environment),
