HOW TO MANAGE DATA SECURITY OF AN EXTERNAL HARD DRIVE BY BLOCKING BLOCKING ACCESS.

Hello all,
Here's my situation:
I have a form with a listbox and a textbox, both related with the same collumn of a databasetable.
When i click an item in the listbox i want the textbox to show the item as well.
I tried the following code in the click event of the listbox:
Me.BindingContext(dsGroepAgent, "groep").Position = lstgroepen.SelectedIndex
When i click an item in the listbox the following error occured:
An unhandled exception of type 'System.StackOverflowException' occurred in System.Windows.Forms.dll
Any idea?

|
|
try this one.
textbox1.text=listview1.selecteditems(0).subitems(0).text
textbox2.text=listview1.selecteditems(0).subitems(1).text
........
Don't block the drive way of all the newbies in programming.

Im trying to enum the childwindows of a application, but when i use the EnumChildWindows in the Windows 32 api i get "A protected area of the memory could not be read"
How is it supposed to be done?
This is what i have so far.
<br />
<br />
' Inside main function<br />
Call EnumChildWindows(ProcessInfo.Handle, AddressOf EnumFunc, 0)<br />
<br />
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''<br />
' The enum func<br />
Public Function EnumFunc(ByVal hwnd As Integer, ByVal lpData As Integer) As Integer<br />
Dim lResult As Integer<br />
Dim sWndName As String<br />
Dim szClassName As String<br />
<br />
EnumFunc = 1<br />
szClassName = Space(MAX_PATH)<br />
sWndName = Space(MAX_PATH)<br />
<br />
lResult = GetClassName(hwnd, szClassName, MAX_PATH)<br />
szClassName = Left(szClassName, lResult)<br />
<br />
GetWindowText(hwnd, sWndName, MAX_PATH)<br />
sWndName = Left(sWndName, lResult)<br />
<br />
Debug.Print(sWndName + Chr(13))<br />
<br />
End Function<br />
<br />
' Deligate<br />
Public Delegate Function EnumFuncDeleg(ByVal hwnd As Integer, ByVal lpData As Integer) As Integer<br />
<br />
Any ideas?
-Thanks

Hello,
I have VS 2005 and using the crystal reports that come with VS 2005.
"The type initilizer for 'CrystalDecisions.CrystalReports.Engine.CRPE' threw an exception"
I have some reports that worked fine a few weeks ago. And now I am getting this error with I never used to.
It can't be anything to do with the code, as nothing has been changed there. I also deployed the application a few weeks ago, and that application is still working on the customers computer without any printing problems.
Can anyone help me solve this problem.
Thanks very much,
Steve

What does the InnerException in this Exception say?
Something got changed, that much is certain. Be it in your code, or in the rest of your dev machine somewhere, but something changed.

Hello,
Thanks for the reply.
The inner exception says: "Could not load crpe32.dll"
But i have this dll when I check in this folder: C:\Program Files\Common Files\Business Objects\2.7\Bin
Yes, I agree something must have changed, but nothing would have been changed on purpose. The code for the report has not been changed at all.
Maybe something else.
Any further help would be most gratefull,
Thanks,
Steve

It looks like you're not alone[^]. It doesn't look like there's a fix yet. You might have to get ahold of BusinessObjects support to get a patch, if it's been released yet.

Hi ...
someone told me that vb.net can make a User's Manual of the projects >>>
I searched without result ....
Can any one explain that ?
thanks for my best foum ..
jooooo

In the strictest definition of "User's Manual", no, it can't.
It can, however, generate documentation files on the code that can be imported into other documentation utilities. But, this is dependant on the code actually having documentation annotations in it!
For VB.NET 2002 and 2003, you have to use a third party tool called VBCommentor (Google it!). For 2005, it's built in[^]. Then, you can use Sandcastle[^] on it.

Am in this Step
"Accepting an input parameter, which needs to be accepted from the user, so the next important Activity is Accepting it from the user and storing it in the string type variable Declared earlier."
Am following a Book instructions and it this is an Example of the Book.
strAuID = Trim(InputBox("Enter Authour ID.:"))
i have Few Questions Based on this Statement.
1)Does the Function Trim ,only works for string Vaiables?
2)Am Accepting User input From a Textbox and here was my code
strNum_key = Trim(txtnumkey)
strExtension = txtextension
strCell_ID = txtcellid
strActual_Extent = txtactualextent
strLis_key = Trim(txtliskey)
strFunc_key = Trim(txtfunckey)
.After i have done this it give me an Error and highlight the above lines, when i comment the first one it highlight the second one and so on.
i need to know what is wrong with my above code compering it with the Example of the Book. Note, all the variables are Well declared,textboxes well named.
Thank you

Trim only works on strings and only returns strings.
Nowhere in your code have you converted a string representation of a number to an actual number.
Dim n As Long
n = Val(Trim(txtnumkey))
This tiny example, of course, doesn't do any validation or handle any errors if the string cannot be converted to a number! This is left up to you.
I highly suggest picking up a book on VB for beginners. I doubt you can find a VB6 book anymore, so you might be forced to move to VB.NET.

Yes i got the Book and am moving to vb.net,i have a vb6 book,it worked when i Put the "Val". now i got another Error in Appending Parameter.
ComLis_key.Parameters.Append prmLis_key
Parameter Object is improperly defined. Inconsistent or incomplete information was Provided
What Does it mean

1)Does the Function Trim ,only works for string Vaiables? trim is only for strings
2)if this is vb.net then you must specify the property .text
strNum_key = Trim(txtnumkey.text)

my misunderstanding...
thanks

Everything is now Ok but i have one Problem, please tell me what should i keep in mind, about the following Errors
"Application uses Value of wrong type for the current operation"
This is th errors in vb6
Set prmNum_key = ComNum_key.CreateParameter("Num_Key", adBigInt _
, adParamInput)
Set prmExtension = ComExtension.CreateParameter("Extension", adBigInt _
, adParamInput, , txtextension.Text)
Set prmCell_ID = ComCell_ID.CreateParameter("Cell_ID", adBigInt _
, adParamInput, , txtcellid.Text)
Set prmActual_Extent = ComActual_Extent.CreateParameter("Actual_Extent", adDouble _
, adParamInput, , txtactualextent.Text)
Set prmLis_key = ComLis_key.CreateParameter("Lis_Key", adChar _
, adParamInput, 50, txtliskey.Text)
Set prmFunc_key = ComFunc_key.CreateParameter("Func_key", adBSTR _
, adParamInput, 8, txtfunckey.Text)
Here is my SQl Procedure code
Create Procedure prcInserting @Num_key varchar(10),@Extension int,@Cell_ID int,
@Actual_Extent float,@Lis_key varchar(50), @Func_key varchar(8)
,@Active bit,@Add_date datetime,@Add_User_ID int,@Spatial_ADD_Date datetime
,@Rateable bit,@Non_Discreet_Valid bit
with recompile
as
insert into Propery(Num_key,Extension,Cell_ID,Actual_Extent,Lis_key,Func_key,Active,Add_date,Add_User_ID,Spatial_ADD_Date,Rateable,Non_Discreet_Valid)
values (@Num_key,@Extension,@Cell_ID,@Actual_Extent,@Lis_key, @Func_key,0,getdate(),1,getdate(),0,0)
And its working only in vb, tell me what to keep in mind with insert procedures that are linked to vb for input

Like I keep trying to tell you, you are NOT CONVERTING the data in the textbox's to an appropriate data type!!
A textobx will always return a string. You have to convert that string into a number with the Val function. Then you pass that NUMBER into the parameter:
Dim v As Integer
v = Val(Textbox1.text)
Set preCell_ID = ComCell_ID.CreateParameter("Cell_ID", adBitInt, adParamInput, v)

Hi all,
in VB2005, how can I asssign the whole object attributes to another object of the same type. For example, if through the code I've assigned the attributes of a DataGridView object (AllowUserToddrows, ...), is there any way to copy them to another Datagridview object?
Thanks in advance,
Marc Soleda

I've never had the need to do this, so a litte research is in order...
There's no way to copy a DGV in one line of code, no.
The most correct way to do this would be to put the code that setups up your grid properties into a shared method, then just pass the datagrid object you want setup by refrence. Done. No need to copy the object.
Other than that, you'd have to create a method that takes a DGV ByRef as a parameter, then code it to create a new DGV object, copy all the properties you want from the supplied DGV to the new one, then return the new object as a return value.
[EDIT]
You could probably do this with Reflection though.
