Access wont support centralized db access for that matter..better use an RDBMS like SQL Server

if i have an image placed in myproject/images/test.jpg, should i also add it in my.resources? if i dont what would be the advantage or disadvantage? and what would be a proper relative path for this image if i dont add it in my.resources?????

You can embed resources in an EXE or DLL project; the advantage is they no longer are
separate files, can't get lost, can't get replaced without the author knowing it, etc.
The alternative is having separate files; easiest way then is to add them to the folder
that contains the EXE/DLL and use relative paths.

You can't stop the user from changing the input language. All you can do is properly handle user input and output and adapts to the new language.

Hello,
In my small VB .NEt 2005 program. MS Access Database is coonnected via "Add New Souce" & added to the project. I have a DataGrid that is bound to a data source (Dataset) and Data Member is (tableName). I retreive data on basis of selection in the List. A query is called & saved based on List Selected item. Datasource of Datagrid is bounded programmatically. I want to add/edit and delte records in the Data Grid. I am not able to update the recor to the table. Dataset is updated. Here is the code to populate Datagrid and Update. On Update button click, UpdateDetails() is called.
<pre
'="" populate="" data="" grid
="" private="" sub="" populatedatagrid(byval="" index="" as="" integer)
="" try
="" retreive="" by="" passing="" category="" id="" and="" save="" in="" set
="" dim="" i="" integer="Me.TblEmployeeTableAdapter.FillByCatId(Me.EmployeeDataSet.Tables("Employee")," index)
="" msgbox("rows="" found="" "="" +="" me.employeedataset.tables("employee").rows().count().tostring())
="" me.employeedatagrid.selectionmode="DataGridViewSelectionMode.FullRowSelect
" set="" the="" dataset="" datasource="" for="" me.employeedatagrid.datasource="Me.EmployeeDataSet.Tables("Employee")
" catch="" ex="" exception
="" messagebox.show(ex.message)
="" end="" try
="" sub
="" update="" details="" called="" on="" button="" event
="" updatedetails()
="" me.employeedataset.tables("employee").acceptchanges()
="" me.employeedataset.acceptchanges()
="" msgbox("updated="" status=" + i.ToString())
End Sub
' aLSO TRIED THIS, BY DRAGING THE TABLE INTO THE FORM AND RESULTED AS MY OWN CREATED DATAGRID
Private Sub UpdateBound()
Me.Validate()
Me.EmployeeBindingSource.EndEdit()
Me.EmployeeTableAdapter.Update(Me.EmployeeDataSet.Employee)
' Me.EmployeeataSet.AcceptChanges()
End Sub
' USER DELETING ROW EVENT OF DATAGRID
Private Sub EmployeeDataGrid_UserDeletingRow(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewRowCancelEventArgs) Handles AlbumsDataGrid.UserDeletingRow
If (MsgBox(" are="" you="" sure,="" want="" to="" delete="" record="" ",="" msgboxstyle.yesno,="" "delete="" record?")="MsgBoxResult.Yes)" then
="" msgbox("record="" deleted")
="" else
="" if
="" sub
<="" pre="">
When user selects a row, and Clicks Del key, UserDeletingRow event is thrown by the grid. I had handled that event & asking for confirmation. Even if the user says "No", the record is deleted at present from the grid. How to stop it. Currently no delte code is written.
1. How do I stop the Delete Action if the user selects No
2. Why is the Upadate not functioning - not saving in the DB.
3. How do I know if the user is adding new row. And How do I insert that row in DB.
4. These all operations need to be done just via Update button.
So, basically I need to Add/Delete/Edit records in DataGrid. Just have a Update button. I have enabled Add New, Delete, Modifiy in Datagrid. Please guide me as what wrong I am doing & what chamges/implementationes need to be done. I don't know how to bind data by default by running such type of query & passing parameter, so have done it programmatically.
Please help me friends. I looked a lot on net, but couldn't find proper solution for my needs.
Any help is appreciated.
Thanks
Terry

I haven't done this myself, but I would think that the answer lies in the e argument of the UserDeletingRow event. Perhaps there is an e.Cancel or something like that, which you can call if the user says NO to the confirm messagebox. I'd suggest using intellisense to examine the e.

Oh Thanks Kschuler. That worked. Thanks a lot. Atleast my Delete part is up & running. I also figured out to Update Databse. Actually the point was, I had to select "Copy if newer" of CoptToOutputDire property of the database.
Now, I am wondering to validate the entered data. CurrentCellChanged is not working as accepted. RowValidating is also not helpful. I added RowAdded event and am able to know. But I can't get how to validate the entered stuff. I have Date & Cost which needs to be validated otherwise Datagrid throws its own Exception. Instead of Datagrid handling it, I want to handle & give appropriate message. Please help me if you can in this matter too.
Thanks a lot
Thanks
Terry

Sorry. I don't do much work with editting directly in a DataGrid. The only advice I've got would be to look through the possible DataGrid events and look for ones that might be what you want, then add code with messageboxes so you can see when the event fires. Perhaps you will find one that fires before the DataGrid throws its exception.
I think you could get away with posting this question again, though. And maybe someone else would be able to help you.
Good Luck.

just put e.Cancel=True in the else part of your code
If (MsgBox("Are you sure, you want to Delete the record ", MsgBoxStyle.YesNo, "Delete Record?") = MsgBoxResult.Yes) Then
MsgBox("Record Deleted")
Else
e.Cancel = True
End If

hi all,
i am developing program with vb.net 2005
i am using combobox and i set the AutoCompleteMode property to Suggest, so when i type something to there, it will appear a list for every the content that likes what i type..
the problem is.. when we click on the list... it will return keycode 13 or enter... how can i disable that...
is anybody have the answer?
Thanks...
|

|
|

You can check for keypress event for combobx and do nothing is keycode is 13...

Hello,
I am not agree ur point. Because In all control's Keypress event thier will be event displayer commonly known as 'e'. if we use e we will get to properties like e.handler, e.keychar. From this e.keychar which will tell the current pressing/pressed key character.
From that we get 13,43,46 asci values which we currently using if we go for asc(e.keychar).
13 - for enter
32 - spacebar
46 - pullstop / dot

hmm.. but i need the 13 keypress event ....

Hello,
It is easy if u follow the changes in the properties of combobox.
1. FlatStyle - System
2. AutoCompleteSource - ListItems
3. AutoCompleteMode - SuggestAppend
after completion of this. I think ur problem may solve

if i use the SuggestAppend AutoCompleteMode property...
when i use the mouse scroll it will not display all item in the combo box..
it just display item that like w type when we scroll it..

I want to temporarily disable the UAC, when i launch my Application and enable when i close the application.

File this under 'not a chance in hell'. UAC is about protecting the user from apps dong unauthorised things. What use would it be, if you could call an API that turns it off, while your app does whatever it likes ? ( no, I don't think you're writing anything malicious, but that's not the point )

Becoz. I have my application while launch it has to register the component before executing exe.
That's why iam asking you. if you have any code please refer me.

Well, apart from the fact that I'd never use VB6 for *anything*, my answer stands. I'm not saying you're writing anything bad, I am pointing out that even if you were not using an antiquated and dead language, you still would not find support for turning off a security feature using code, it's just not going to happen.

That should be done during the installation phase. Installers run with elevated privilege.

As Christian already said there is no code that will disable security procedures without the proper rights in place. If you want to disable a security feature you must already have the rights to do so. In order to get those rights you must go through UAC.

What part of "IT CAN'T BE DONE" is so hard to understand??
Your code is not allowed to just "turn off" the UAC whenever it wants.

hi all,
I want to make a program that can list all current connections and block/allow a program from connecting to the internet.
can anyone give me a tip where can I start ?
I've been doing some tricks with the xp sp2 firewall, but now I want to develop something that doesn't depend on it.
thanks

Your first going to have to learn to write drivers for Windows. Dig up the Windows Device Driver Development Kit, learn C++, learn to write drivers, then learn how Window's network stack works and write a driver that will fit between two layers of the stack so you can intercept all the network traffic and analyze it before it gets sent up the rest of the network stack.
THEN, you can write your app to analyze the traffic and modify it.
