I have a datagrid which has a column called "tick". There is a button which will "ticked" all the the records in the datagrid so the user don't need to do it one by one.I have been reading MDSN but I am more confuse that before.my old vb6 code was:
On Error GoTo cmdTickAll_Click_Error
Me.MousePointer = vbHourglass
'Loop Through and Set all Ticks the Not Ticked[code].....
So a timer's maximum interval is 1 which is a thousand ticks a second. A Stopwatch's frequency is 2238906 ticks a second on my pc...
I am wondering if there is a reliable way to trigger an event for each tick of the stopwatch without missing any ticks...
If I can somehow get a Tick event for the stopwatch, I believe I can increase the resolution of my input recorder....
Right now I am doing the following.
Inserting records one at a time. See below
I am trying to figure out how I can update in one connection.
Public Shared Function saveserver(ByVal servlist As List(Of server)) As Integer
Using myconn As SqlConnection = New SqlConnection(ConfigurationManager.ConnectionStrings("Citrixmanagementlocal").ToString)

Using Microsoft Access2007 as database, VB 2010 WinForm (DataGridview + Textbox)
There are a lot of record need to be Updated, It is very efficient if that data is just going through Batch Update, meaning just one click will update all the data rather than click one by one.
Any Demo or code showing how to do this Batch Update (VB.net).
I am trying to update a table across "non" linked SQL servers using:C# or VB.net and ADO.net sqlDataAdapter.
I need to use DataTables and sqlDataAdapter.Very Important I need to use BatchUpdate and avoid looping through the DataTable
The table designs in Server 1 differ from table design in Server 2.
Source Table
Server 1. Table 1
ID INT[code]....how to update table 2 on server 2 using a sqlDataAdapter, or alternative batch method?
I am using VB.Net 2008 and ADO.Net to do a Batch Update to our Oracle database. The updates are working, but there is a trigger on the table before the row is updated to enforce a member's termination termination date. So if I was trying to set the termination date (via the batch update) to 31-Jan-2010 but the member had a claim that was processed on 2-Feb-2010 the trigger would force the termination date to be 2-Feb-2010. However, the trigger is NOT executing when the batch update runs?Is there any Oracle DB Admin option that would disable Triggers on Batch Update?
View 2 RepliesI want to know is there any functions or methods that i can use to batch update the data to MS access from vb.net 2005?Here is my case:I have around 70 records to update back to MS Access.Currently I only know update row by row. So, it means i need to loop through all rows. (I also have where ...=... and ...=... and ...=... in update command.)Its not a good idea because if some where went wrong during updating.The previous updated data will be in DB but the rest will not. So, data will not correct and up-to-date.So, I want to use Batch processing. If something go wrong, all will not update. If updating is OK, then all will be in DB.
View 5 RepliesI am setting a timer interval of (Hours):
Timer1.Interval = ((CInt(ComboBox24.SelectedItem.ToString()) * 60 * 60) * 1000)
And then calculating the next DateTime that the ticks event will fire using:
MessageBox.Show("Next Timer Will Occur At: " & New Date(DateTime.Now.Ticks + Timer1.Interval))
Each time I call the MessageBox it shows me that the next event will fire now (Exact date, hour, minute, second).I can't see where I have gone wrong here as when I simply messagebox'd the calculation it clearly showed separate numbers (ticks) & by a large amount.

View 20 RepliesI have an access database that has columns where the data is a tickbox, i would like to select all the ticks from one row. Erm i'll try and be more descriptive: The database has the family of aircraft in the first column and then each subsequent column is to do with a calculation and i want to assign boolean variables the value of true if the tick box is checked and false if it isnt. How can i assign the values of the tick box to a variable?
I have this query:

View 8 RepliesOk i know your all denying knowledge of VB6 here but it still exists and people are still stuck with it for now! Plus youre a brainy bunch so i hope you can help, it is more .Net related anyway i think.Ok ive inherited an old VB6 app that needs to access a VB.Net dll and im having issues with it!Ive compiled the DLL and made sure all the Com boxes are ticked so ive now got a .DLL and a .TLB file.
Now when i load up the VB6 app and go to add a reference to the TLB file it makes the reference ok but when i run the app i get a "xxxxx.dll cannot be loaded" error when it hits code trying to use it.What ive tried is running Regasm against the DLL with the regfile option to generate a registry file that i can load onto my machine but it still gives that error.
im not sure exactly how to get a .Net dll into vb6 tbh so im just fumbling my way with it. What i think has happened is a previous version of the DLL was registered on the machine, has since been deleted but the system is still trying to use the earlier one, reference pointers still around?
So my questions are 1. how can i clean the machine out , apart from formatting it!, so i can register the new DLL properly and cleanly on it. 2. What exactly is the right way to get a .Net component into an old VB6 app? I was assuming it was by using the TLB and making a reference to that, it wont let me add a reference stright to the DLL itself.

There is a radio button on a webpage, if the radio button is ticked I need the app to refresh page, if not then do other stuff.
This is the html of the radio box

CODE:
in the program im trying to make i have a button that when clicked starts a fairly lengthly loop, takes a couple minutes to complete. while this is happening im trying to send the an update of the loops progress to a listbox i have setup. Unfortunately these updates dont make it to the list box until the loop is finished, ive tried this with a few different types (progress bar/ rich text box etc). i cant seem to get any form changes through while the loop is in progress.
Is there some option or event thing i need to specify to be able to make changes to the form while in a loop?
I am not getting any errors. But the update query is not executed as it does not change the database.

I have a program which I'm designing to help organize and move some of my music around. I can create a play list and then add music to it, when I do this it copies the mp3 files to a specified folder and also updates a listbox with the content of that folder.
The code works, however when I run it the program locks up until everything has been copied, the listbox goes from blank at the start to suddenly showing the whole list.[code]...
I'm working on a problem for my class, I've been stuck on this for hours so I've determined I would post here
I need the program to subtract 20% when a non profit check box is ticked (chkNP in my case)
I have the rest of the app functional:
CODE:
Basically the application is a tool or determining the cost of packages from an ISP
Package A: 10 hr access. $9.95 mo. $2 each additional hour
Package B: 20 hr access $14.95 $1 each hour
package C : unlimited. $19.95 a mo
So basically the app needs to apply a %20 discount to each of these when that checkbox is ticked

Basically I am trying to update each record with 2 random numbers each time the button was clicked,my problem now is, the system will update the record but the data was wrong. Example, by right all data should be different (randomly string) but for some row it was updated with same data but in randomly, something row1 row2 row3 has exactly same data for column 1 and 2 then row 3 has distinct data, second time, row1 row2 same data row3 ro4 with different data. It is in random sequence. When I add a MsgBox to do testing in the For loop the data was updated correctly with all different data.
How can i make it so that label1.text = the number of time timer1 is ticked ?

View 5 RepliesI am working on trying to update a list of items to an Excel spreadsheet. I have created my own custom class called Songs and a List(Of Songs) that I want to update the spreadsheet with. It seems like everything is working -- I have even put in a debug msgbox that displays what Song it is currently on while iterating thru the loop -- but after the code iscomplete, I check the spreadsheet and only the first song in the list gets updated. I'm thinking it must have something to do with either the connection string or the parameters that prevents it from updating any other song records. BTW, there is no errors being tossed so it ats like it everything is being processed, just that the data doesn't change for the update inside the loop. Here is the section of

I am using a loop to update properties of each object of a set of custom objects. The routine knows which controls to update because the controls value is not empty, I don't want the routine setting the corresponding properties to nothing when the control is empty. Now I know how to do this perfectly fine with IF statements such as:
CODE:
But this feels really redundant doing that same IF block over and over for each property/control combination, I thought about creating a separate routine that takes the control as an argument and does all the repetitive IF blocks but I don't know how I could also pass an object property to tell the routine to update that particular property.
