Show Package Detail With Customer Name On Button Click
Jan 17, 2011I am writing a program about dog grooming. There are three levels: puppy package, economy package, and the spa treatment package. I have created a database with the customer's name and desired package already. I would like to create a program, that with a click of a button, will show each package detail with the names of the customers. For example: 10 customers that want the puppy package. I want it to loop from one to the last with each button click and place it in a list box.

Place / Drop An Image Every Time Click The Mouse Button?
Feb 9, 2012I looked at "How do I place an image with a mouse-click in Javascript?" but it had a small snippet of Java; immensely larger than my knowledge of Java. And that is the closest I've come to finding an answer in the past week. Here's what I would like to do (don't know if its even possible):
I have a panel and a toolstrip with 3 buttons. Each button represents a different image. I want to click on a button (once) and then move into the panel and everytime I click the mouse button it drops the image where ever I clicked. This only ends when either I click back on the same button or one of the other buttons. I do not want to drag an image into the panel each time. In other words the button stays depressed and the event/action stays active.

Cannot Insert / Update Data On Detail Table Via Master-detail Form
Nov 12, 2011I use a simple master-detail form using Visual basic 2005 express edition and ms sql server 2005 express edition, as well.
The master table is dept (deptno int, dname nvarchar(50)) .
The deail table is emp (empno int, deptno int, ename nvarchar(50)).
The primary key for the dept table is deptno and for the emp table is empno.
There is also a foreign key (deptno on emp table).
I created a new project, connected to a db (called test.mdf) and created a data source consisting the two of the above reffered tables.
I dragged and dropped these tables on the form and i noticed the following:
1)When the form opens... the system queries the database and displays the data on each block on the form.
2)I insert and/or update a record on the master table (dept) and everything goes well...
3)I try to insert and/or update a record on the detail table (emp) and nothing is changed on the detail table - without any error.
4)When i try to insert and/or update a record on the detail table (emp) which violates the primary key constraint or foreign key the system complaints...(as expected).
DB/Reporting :: Master - Detail Data - Overwrite The Primary Field Value In The First Grid And The Detail Records
Jul 13, 2010I have made several posts on here lately regarding master/detail or parent/child data setups but no one has been able to help. It seems like a subject people don't like to tackle BUT I really need help.
I'm having a real hard with the DataView.RowFilter functionality and it is driving me insane.
For the most part, I have the basic master/detail functionality working. When you select a record in the first grid, it shows the correct data in the second grid. When you enter a record in the first grid, you can enter related data in the second grid. I accomplish this by using a dataview and row filter bound to the 2nd grid. When you change the record in the first grid, the rowfilter for the 2nd grid is restated and reapplied.
The problem arises when I overwrite the primary field value in the first grid and the detail records become orphaned. You would think all I have to do is change the ID in the 2nd grid to match the new ID in the 1st grid but this is where I am having problems. I wrote a loop to change the ID of each record currently loaded in the 2nd grid to match the newly changed ID in the first grid. The code is here:
Code:
Dim I As Integer
For I = AuthorizationGroupsDGV.Rows.Count - 2 To 0 Step -1
AuthorizationGroupsDGV.Rows(I).Cells(0).Value = StrEmployeeID
Next
I have used this code before and it works great. It has to step backwards through the grid because when the ID's are changed, they no longer match the RowFilter criteria and they disappear from the grid. They still exist in the dataset. The problem is, while the code "works" the intended effect does not. Some of the records completely disappear from the dataset and do not reload when I restate the row filter against the new ID number.
