Can anyone tell me what happen when i do following code?
SqlCommandBuilder1 = New SqlCommandBuilder(SqlDataAdapter1)
SqlCommand1.CommandText = "select * from phieumuonsach "
SqlDataAdapter1.InsertCommand = SqlCommandBuilder1.GetInsertCommand
SqlDataAdapter1.Update(DataSet1, "phieumuon")
|
|
|
|
|
Not enough information to answer the question with any meaning.
But, it looks like it's supposed to update the backing database with any changes in the phieumuon table in DataSet1.

First of all this is incorrect it seems that you don't know what you are doing there.
First what are you trying to Achieve here
SqlCommandBuilder1 = New SqlCommandBuilder(SqlDataAdapter1)
Does not make sense. Secondly you came up with this
SqlCommand1.CommandText = "select * from phieumuonsach "
This means you are telling your command object that you never declared that you will be using that SQl statement. and what kind of Command object is that (i dont know you did not state it)
thirdly cam up with this
SqlDataAdapter1.InsertCommand = SqlCommandBuilder1.GetInsertCommand
Here you are trying to tell the Adapter that you are going to use which Command for Insert. a bad way of doing it.
lastly
SqlDataAdapter1.Update(DataSet1, "phieumuon")
Here you are Updating the Dataset called "Dataset1" and that has a Datatable named "phieumuon"
if this is a Complete code then it will not compile because it does not make sense

Well, you have 2 choices:
a.) Buy a book on JavaFX, get the specs form your teacher, then do the work (if you problems with something, go here[])
OR
b.) drop the class and NEVER write another piece of code again.
|
|
|
|

Well, I suggest you start writing it! Noone is going to hand over their hard work for you to turn in as your own so you can pass your lazy ass through a class you don't deserve to pass.

I'm sure you do. Why you expect us to provide it, in response to a post in our VB forum, I am not sure.

Contact your client and tell them you are a liar, and offer a refund. Then apply for a job at McDonalds.

Hi
I'm using the dwm api to get another application's "form" on my application. It's working great so I have the vista/windows 7 preview window on my application. But I'm now trying to get a screenshot of my application and saving it to a file. When I try to accomplish this I get everything (buttons,pictureboxes etc) but I don't get the preview window (the other application's form).
I have searched around to get some information about how the DWM Thumbnail works, and it seems like it isn't alot information around. What I do know is that the DWM Thumbnail is creating a constant connection between my application and the source application.
My question's are.
------------------
The picture information I get from the DWM is it available in my application or is somehow rendered directly to the graphic card, and isn't really sending the info to my application.
Is it possible to print a screenshot of my application that will work even when my application is not ontop?
Best Regards Henrik

I have use Text box to my project and i want to implement Undo method of the textbox. When i check CanUndo property of the textbox it always return false.
somebody tell me how can i enable undo method to my textbox.
|

It helps to read the documentation on the TextBox class. Undo has already been implemented.
CanUndo tells you if the last operation the user did in the TextBox can be undone or not. It does NOT enable or disable the Undo functionality of the TextBox.
In whatever code you have that lets the user command an undo, you have to check the CanUndo property of the TextBox and then, if true, call the Undo method of the TextBox. You would also look into calling the ClearUndo method if appropriate in your situation.

Hi mates,
What tools are available to convert Access projects (Forms, Code, Queries,Reports) to Vb.net?
I have a new project now, its an mdb file, they want me to work on vb.net. An access application running in Access 97.
Is this possible to convert in vb.net? It has 20 forms, 50 tables, 200 queries, 4 reports, and 10 modules.
If I will do it in manual it takes a months to do this.
Can anyone tell me how to approach this kind of project.
or should i start from a scratch>?
Thanks in advance.

i don't know of any tools that will do this, however even if there is one I would not use it. The tool from VB6 to dotnet was dodgy so Access to dotnet would be just plain nasty. Besides how would the tool deal with the database object, tables and queries and reports?
Take the opportunity to write from scratch, you almost certainly will need to anyway.

Redesign and rewrite. A rewrite opportunity should always be taken, almost all apps can benefit from a rewrite/refactor.

Yah, a newbie would be looking into that upgrade/wizardy thing and praying, you are right, reality is you have to rewrite. Look on the bright side, at least the specs are fairly solid.

Hi All
I have a problem....
I want to add a dropdownlist to a datagrid in a GUI application.
This can be done using the [DataGridViewComboBoxColumn Class]
But my problem is this class is only available from .Net Framework 2.0
And i can only use Framework 1.1 
Is there any workaround i can use?
I thought about designing a new DataGrid(by Inheriting the standard DataGrid Class)
Is this possible or is there another way to do this?
Any help would be appreciated.
Regards,
Josef

Dear All,
Now I want structure to similar treeView or listview but the format is like that:
Company_ID------Company_Name----Address--------xxxx------xxxxx (Note: Filed Name)
+ 001-----------Com A-----------st154----------xxxx------xxxxx (Note: Record)
------- + contact Person
--------|------Name------------Position--------Email (Note: Field Name)
--------|------Mr A------------Admin-----------mr.A@yahoo.com (Note: Record)
--------|------Mr B------------Finance---------mr.B@yahoo.com
--------+ Products
--------|------Name---------Kind--------Expired-------xxx-----xxxx
--------|------Pro A--------A-----------1/1/2010------xxx-----xx
--------|------Pro B--------A-----------1/1/2010------xxx-----xx
--------|------Pro C--------B-----------1/1/2010------xxx-----xx
+ 002-----------Com B-----------st154-----------xxxx------xxxx (Note: Record)
--------+ contact Person
--------|--------Name--------Position--------Email (Note: Field Name)
--------|--------Mr C--------Admin-----------mr.A@yahoo.com (Note: Record)
--------|--------Mr D--------Finance--------mr.B@yahoo.com
--------+ Products
--------|--------Name--------Kind------Expired
--------|--------Pro Q--------A -------1/1/2010
--------|--------Pro W--------A --------1/1/2010
--------|--------Pro E--------B --------1/1/2010
Example above is have 3 tables but there relation by Company ID
When I click on + the sub (contact person, Product, and ...) it will show.
and when i click on + of subs (contact person or product...) it will show their data.
I would like to say sorry if my wrote is not clear.
What any tool that can make like that ?
Can you send me the source code ?
Thanks you.

I would have thought a dataGridView would be a better solution than either Tree or Listview.
Infragistics has a an OutlookExpress style on their treeview that will allow a treeview with columns.
There is an A Much Easier to Use ListView[^] here on CP that does the same and it is free.
