I have upwards of 60 controls on an asp.net page, a little under half being checkboxes, a little under half being labels, and a few textboxes. Going through manually and clearing them if a giant pain, and I know there has to be an efficient way to clear them, like using a For Each loop, checking the type of control, then taking the appropriate action (ie. .Check = false, .Text = "", etc). Problem is I'm pretty new to the .Net framework and I'm not exactly sure how to reference the controls.
Any ideas? Thanks in advance.

Hello!...
try this one..........I am considering that you have these all these controls in some parent control like GroupBox.
Here is the code
Dim ctrl As Control
For Each ctrl In GroupBoxName.Controls
ctrl.Text = ""
Next
Now for differentiating b/w the controls say Textbox and Checkbox etc it would be very easy if you have some meaningful control names e.f textbox name starts with 'txt' and checkbox with 'chk' or whatever......If this is so then you can check for the control names for finding out the type of control.......
I hope this will solve ur problem

Thanks for the input! I'm one step closer, but not quite there...
Actually, they're inside in an HTML table inside a Form. I'm pretty close with the logic, I just can't seem to finagle the reference to the form correctly. Here's what I have:
Dim ctrl As Control<br />
For Each ctrl In Page.Form1<br />
If TypeOf ctrl Is CheckBox Then<br />
CType(ctrl, CheckBox).Checked = False<br />
End If<br />
If TypeOf ctrl Is Label Then<br />
CType(ctrl, Label).Text = ""<br />
End If<br />
If TypeOf ctrl Is TextBox Then<br />
CType(ctrl, TextBox).Text = ""<br />
End If<br />
Next
the Page.Form1 is what it's getting caught up on.
Any ideas?
abort, retry, fail?

got it!
the reference is: Page.Controls.Item(1).Controls
Item(1) being the form.
thanks for your help!

Wow, before now i didn't realize Visual Studio 6.0 was still that expensive if you tried to buy it. You could look on <shudder &="" cringe=""> eBay . Just try to make sure you are getting a legitamate copy under legal terms (could be more work than it's worth). Otherwise, you could just use a good old text editor with syntax highlighting ( i.e. http://gobby.0x539.de/index.html[^].

VB6 != VS6
VB6 (Visual Basic) Apps can only be compiled by the VB6 compiler. Visual Studio (C++) apps can be complied with just about any standard C++ complier.
With .NET it’s a little different; you can use any standard text editor to write your apps. MS offers a free complier for .NET.
So to directly answer your question you need a licensed copy of VB6 to compile the apps. If you’re new to programming and have a copy of Visual Studio 2003 then I suggest learning VB.NET there are some significant changes to the VB language. Learn once not twice.
If you do decide to learn VB.NET then there are a variety of options for you. Get a .NET IDE and search MSDN.Microsoft.com for the free complier.
Good luck and happy programming…

I am using VBA Excel 2003
I have the following code within a module:
ActiveWorkbook.XmlMaps("config_Map").Export URL:= _
"C:\TextXML.xml"
It works great....ONCE. If the file does not exist, it works exactly like I want it to. However, if the file DOES exist, it throws this run-time error:
Method 'Export' of object 'XmlMap' Failed
How can I get this to overwrite the existing file? Thanks in advance.

Tell there is a second, optional, parameter that specifies whether to overwrite the file or not. If not specified, it defaults to False, which is no overwrite.
ActiveWorkbook.XmlMaps("config_Map").Export URL:= "C:\TextXML.xml", Overwrite := True

I am trying to add the asscociated file icon in the listview(
lvwFileNodeList ).
I successfully add the icon for the first found file, but for the rest it
uses the
same icon to display the associated icon. As the following, i am adding the
file icon in the image list with the extension as a key and add this icon
when
adding this file to the list view. there must be the extra step i have to do
does any know what 'm missing?
my envrionment is vb6/xp pro
Me.ImageList2.ListImages.Add , FindExtension(strFileName),
GetIcon(strFilePath, SHGFI_SMALLICON)
Set objListItem = Me.lvwFileNodeList.ListItems.Add
objListItem.SubItems(3) = strFilePath
objListItem.SmallIcon = FindExtension(strFileName)
Public Function GetIcon(filename As String, icon_size As Long) As
IPictureDisp
Dim index As Integer
Dim hIcon As Long
Dim item_num As Long
Dim icon_pic As IPictureDisp
Dim sh_info As SHFILEINFO
SHGetFileInfo filename, 0, sh_info, _
Len(sh_info), SHGFI_ICON + icon_size
hIcon = sh_info.hIcon
Set icon_pic = IconToPicture(hIcon)
Set GetIcon = icon_pic
'GetIcon = sh_info.hIcon
End Function
' Convert an icon handle into an IPictureDisp.
Private Function IconToPicture(hIcon As Long) As IPictureDisp
Dim cls_id As CLSID
Dim hRes As Long
Dim new_icon As TypeIcon

i want to execute an executable file from the interface created in VB.net.
i have an exe file named first.exe which needs to be called from a click of a button.
i found the general command for it.. as Shell("C:\first.exe",<parameters>)
this works fine.
what i want to do is try to execute the following command written in dos:
c:\> first < in.txt
and
c:\> first < in.txt > out.txt
thru VB button.
i need help for this.. urgent... :confused
|
|
|
|

Try specifying the command line parameters in the Shell() statement thus:
Shell("c:\first.exe < in.txt > out.txt")

i tried that but it didnt work..
i'll explain my problem better..
- the in.txt contains few lines of code that is executed by the first.exe file . this exe file gives an output which i want to save in out.txt
problem with the suggested command
it opens the editor of the first.exe file rather than creating out.txt file which is not what i want it to do..
or is there any other command which allows us to perform my above mentioned task thru click of a button in VB.net
|

Ok, so first.exe reads in.txt and writes out.txt? How do you normally specify the input and output to first.exe? Is it a commandline program which expects these parameters or are you trying to get it to work differently from the way it was designed? If you have the source code for first.exe you can reprogram it whichever way you want but to call it from VB (or any other program for that matter) you'll need to adhere to the calling conventions expected by first.exe.
What you may need to do is to execute first.exe via cmd.exe thus:
Shell("cmd.exe c:\first.exe < in.txt > out.txt")
...Steve

well.. on double clicking the first.exe it opens its own editor (black wondow) where input is given and its output is displayed in the same window below the input lines of code.
the input can also be provided thru a file. i.e. type in the input text and savin it as in.txt and givin the followin command in cmd gives the desired output in the editor of first.exe file .
C:\> first < in.txt
to capture the output in a file. the followin cammnd works fine in cmd;
c:\>first < in.txt > out.txt
it creates the output file out.txt just fine..
i had wanted to do the same thing thru the Shell("c:\>first.exe < in.txt > out.txt") but it only opens the exe's editor but doesnt create the out.txt file,... the in.txt file has the input written and saved already...
i hope u got the clear picture.
may b i need to reprogram the first.exe file itself...
regards

If you're going to use the redirection operators in a command line, you MUST launch your command inside a command shell (CMD.EXE on NT-based machines).
Shell("cmd.exe /c c:\first.exe < in.txt > out.txt")

I created a connection using OLE DB (ADO) to a password protected access database. I designed a report using Designer support. It is throwing error described as under:
Logon Failed.
Details: ADO Error Code: 0x80040e4d
Source: Microsoft JET Database Engine
Description: Not a valid password
SQL State: 3031
Native Error: -124782449
I am sure that I am not suppling password to report viewer. But I do not know the way.
And, Can I filter records at crystal report level?
Any Body Can Help Me.

Sounds to me that the connection string to your access database is not in correct syntax.
