DataGrid1.DataSource = dataenvoriment1<br />
DataGrid1.DataMember = command1<br />
DataGrid1.DataBind()

I have windows form (vb.net) in which i have webbrowser control. Now when i open up some web site at runtime in that form, i need to capture the onblur and onfocus events of my input boxes on an html form and perform custom external handling in my vb.net application. I have been able to successfully hook up a handler to the 'onclick' event, but the 'onblur' events are not working. Can anybody please tell me why is it happening?
i have picked up an input box and then attaching an evenhandler using
AddHandler CType(txt, mshtml.HTMLInputTextElementEvents2_Event).onblur, AddressOf Me.txt2_HTMLInputTextElementEvents_Event_onblur
and the correspoding handler is like this.
Private Sub txt2_HTMLInputTextElementEvents_Event_onblur(ByVal pEvtObj As mshtml.IHTMLEventObj)
.....................
........some code will go here .......
.....................
End Sub

i haveing an error while running my coding which is to pass the info from the data grid to EXCEL... it pass correctly at first but when it try to pass the last 3 row then error pops up : Runtime error '6148' invalid row number. when i try to check my excel the last print out b4 error happen,it refer to the data grid last row info which mean it try to skip to the last row... so when the system try to read next time there was no more line to read... i have check my code many time i dunno y the vb just skip the line itself....
For example again: datagrid row 10 = EXCEL row 10 but the EXCEL row 10 have print out datagrid row 20...
i = 3 'ROW<br />
j = 2 'Column<br />
For dr = 0 To (Adodc1.Recordset.RecordCount - 1)<br />
For dc = 0 To (DataGrid1.Columns.Count - 1)<br />
<big>DataGrid1.Row = dr</big><br />
DataGrid1.Col = dc<br />
ApExcel.Cells(i + 1, j).Value = DataGrid1.Text 'Pass info from data grid to EXCEL<br />
j = j + 1<br />
Next dc<br />
j = 2<br />
i = i + 1<br />
Next dr
|
|
|
|
|
use :-
For dr = 0 To (Adodc1.Recordset.RecordCount - 1)
For dc = 0 To (DataGrid1.Columns.Count - 1)
DataGrid1.Row = dr+1 ' as 0 is not a valid row

the code which i have underline it.
I know y there is an error because when i read there is no more information cause it have skip to the last line which i did not ask it to do so... so i not sure happen with the system....
when i run the system i check one by one... example, suppose it will pass 14 row with 5 column information each of it.
when it goes to row 12, then the first 2 colum data which is not the correct one the vb itself have skip to row 13-14 and get the value. after that sure it will have error becasue when it try to read the row 13, but the arrow have been point to the last 14 row b4 when it put the value to row 12, so the next data will be 15 which is an empty one.

I am not entirely sure I understand your problem, but should not you put the line "DataGrid1.Row = dr" between
"For dr = 0 To (Adodc1.Recordset.RecordCount - 1)"
AND
For dc = 0 To (DataGrid1.Columns.Count - 1)"
so that the row is changed after all the columns are processed?
Hope this helps.

at first the DR which mean the row~ since i'm showing the data in the datagrid first, then pass to EXCEL.
DC which is the column , which there is 5 column.
when goes to row 1, then pass the datagrid column data to excel, after passing the row 1 column data, then next dr which is ROW 2.

try this
for dr =0 to datagrid1.rows-1

The problem is that your assuming that a DataGrid row is the same as a Row in the Dataset. It's not. You shouldn't even be getting the data out of the DataGrid. Just use the RecordSet object as your source of data to copy to the Excel sheet. The DataGrid is just for showing and editing what's in the RecordSet, keep it that way.
Now, since you're using VB.NET, why are you using the old ADODB objects when the .NET Framework provides much better and easier to use DataSet classes?

Hello,
I have to deploy my application and have been instructed to use merge modules. As the client computers don't have any CR on them. However when I right click on the setup project and add merge modules. There are no msm files for crystal reports.
Can anyone tell me what should I do to add these files, so my project can be deployed and ran on the clients machines.
I am using VS.Net 2005 and Crystal Reports 10. I have been told to enter a lience key. How do I do this?
Thank in advance,
Steve

Hello there,
I have a VB app that creates and runs MS PowerPoint 24/7. When I first started, the application runs Ok as I expected, but then sometime the COM's error from MS PowerPoint throw an exception such as "PowerPoint currently experiencing the problem. We are sorry for the inconvenience, bla, bla... Click Ok to restart the MS PowerPoint", and the system is hung till user must click Ok to dismiss the error dialog box. Since this application runs 24/7 so in the middle of the night, there is noone there to click the OK button to restart the PowerPoint.
I am trying every posible ways to prevent this error to show up such as kill the PowerPoint Object and reinstantiate, reboot host if error happen... Howerver, none of my code worked since the system was hung unexpectedly because MS PowerPoint throw the error and system was hung before the pointer returned back to my code.
I am wondering if there is any way I can sense the error message from PowerPoint and prevent it before it shows up as the error dialog box. Or is there any way I can send code to click the Ok button to dismiss the error diaglog box. Please give me some advice where to start, or point me to some direction. I know there are messages que but I don't know how to access them and how to find the ID of the error windows. I am totally lost in this part now. Please give some advice.
thanks in advance for reading this message

Why are you running the powerpoint user interface on the server in the first place? Doesn't it have any API?

Thank you for the question Guffa.
This is the spec from the user. I can not change it. Here is how it works
VB.Net reference to PowerPoint Primary Interop Assembly
when VB exe file starts, it loads up the PowerPoint show
PowerPoint object plays the show.
There is also a timer instantiated when the VB form created.
When the timer tick, VB exe file goes to same place to see if there is new show created. if there is new show, stop current show and play new show.
The error of COM's problem just throw whenever it wants, and I have no idea how to work with it anymore.
thanks again for reading my message
