I don't know whether am I asking too much but when asking about this question, I have a major problem with getting data from a table. The reason I wanted to identify <td></td> is because of the columns that hold the data I wanted, the code snippet is like this:
<table border="2" cellpadding="1" cellspacing="1" style="border-collapse: collapse" bordercolor="#808080" width="100%">
<tr>
<td width="40%" colspan="4" bgcolor="#FFEFCE" align="left">
<b>Policy No</b></td>
<td width="40%" colspan="4" align="left"> 12345678</td>
</tr>
I wanted to extract 'Policy No' and '12345678' and save it into database but there are tons of row like the above and some are not relevant to my search. I try to split them into group like those with <b></b> is the name for that row and those without it is the value to that row, but it does not work either as there are other <td></td> with value that I don't want to retreive. Example:
<td width="100%" align="right" colspan="2"><font color="green"><b>John Smith, 03/06/2006</b></font><br/><hr/></td>
The code snippet I have is from another programmer and I can't ask him to alter any thing on the page. Maybe I can get some idea from you if you don't mind, I have been cracking my head for a algorithm for 3 days now, just can't find any best idea.
Anyway, thanks for the info, Ed, and the guidance too. It's my first time using VB.NET and this Regular Expression method. I'll go through those articles you told me, need to learn thoroughly about this Regular Expression.

Hi all,
I have a ToolStripMenu in my application. I would like to change the
cusor from default to help cursor when i click on a item in the
ToolStripMenu. I was successfully able to change the cusor, but when
moved the cursor on certain items, the cursor again changes to default.
When moved away from such items, cursor changes to help cursor. I later
found that the help cursor remains unchanged for items which has help
for those items are enabled.
So when i move the help cursor to a toolstripmenu item, cursor changes
to default cursor. I would like to know how to avoid this change in
cursor when moved to toolstripmenu item as there is no property to
enable help for a toolstripmenu item.
I would appreciate your help in this regard.
Thanks,
Sugan

How did you change the cursor? Have you used Cursor.Current = ...?
|
|
|
|
|
I used the following.
Me.cursor = system.windows.forms.curosrs.help
What happens when i use this is cursor changes to a help cursor. But when this cursor hovers over components which does not support help, it changes back to default cursor. For a toolstripmenu item there is no property available in .Net 2.0 version to enable help for that component. Hence when i move the cursor over it, the cursor changes back to default cursor.
Pls help.
Thanks,

Try setting Cursor.Current = Cursors.Help instead. It changes the cursor for the whole application.
|
|
|
|
|
In fact
Cursor.Current = Cursors.Help
does not work at all.
Only Cursor = cursors.help works.
Even then, when i move the cursor to a menu item in the form, the cursor changes back to the default cursor. When i move out of the menu item, cursor changes to help cursor.
Thanks,
Sugan

Hi All,
Can anybody tell me what the meaning of this code snippet is?
<system.diagnostics.debuggerstepthrough()> Private Sub InitializeComponent()
In the above what this ‘<’ and ‘>’ indicates.
Thanks in advance.

they specify the opening and closing declaration for an Attribute (in this case DebuggerStepThroughAttribute) which adornes the method.

It's a metatag. there are certian tags taht handle specifics about how a class compiles and integrates into the VS Environment. for instance
<catagory()>
before a public property causes the propety to show up in the forms designer properties window. that is evidence that VS is prebuilding certian parts of an object to facilitate its WYSIWYG interfaces (like to provide intellisense on new components, custo user controls etc.) the metadata tells the environment which parts to pre-compile in this case.
Web service methods use a similar tag to indicate that teh code gen should create an XML interface and description of the method so it can be enumerated to clients and called via soap.
Think of it as Code defining Code. that is what meta means in any sense. metadata is data about or describing data. gives me a headache myself...
hope that satisifies your curiosity,

Hi all,
In aspx file I have a Data grid. Of which two columns are Template columns. Both of these columns contain Label and Drop down list. On non-edit mode label will display the current information present in the DB. On clicking edit, it will change to Drop down list, giving option to make changes to that particular column value. Now list of items in the second template column drop down list must be populated on the basis of first column drop down box selection.
Eg: first column lists countries then on selecting particular country, second column must display states which belong to the selected country.
Also I have set the drop down list property AutoPostBack = True. So eah time when I change the country it sends it back o the server. But I am not getting any even handlers to handle the even triggered.
Can anybody help me out?
Thank in advance,
Regards,
Krishnaraj

ASP is not my specialty so I can't address the edit-mode or the postback, but for the events, the short answer is to:
create a custom control that inheirts your first Template collumn.
add a public delegate and event within it. raise the custom event on the first templatecollumns changed event.
public delegate sub delIndexChanged(sender as object, e as system.eventargs)
public event evtIndexChanged as delIndexChanged
Private thing(sender as object, e as system.eventargs) handles me.selectedindexchanged
RaiseEvent me.evtIndexChanged(sender,e)
End sub
in your mainpage (the one with the grid), Replace the template col reference with one to your custom control.
once you instantiate the grid cols, add a handler for the evtIndexChanged that points to a sub with
AddHandler MyGrid.cols(idx).evtIndexChanged , AddressOf <subname>
where <subname> has the appropo parameter list for the delegate signature.
that will fire whenever the first col changes. I would use it to gen a filterstatement for a dataview.
to fire the col directly you can just RaiseEvent Object.Event(parameters...) I think. postbacks will complicate this.
I just read somthing about the asp2.0 callback model, and they claim there are now ways to update stuff on the UI (via server side processing) without posting back on the client. you may want to look into it but as I said web isnt my area of expertise.
Hope That Helps,
FrankyT

I have installed Visual Studio 6.0.
While I am opening a VB project, it is displaying only the code behind; not the user interface. While double-clicking the form in the project window, it displays the message-<The instruction at "0x004581f1" referenced memory at "0x00000000".The memory could not be read.>
& as I am clicking ok,the project is closed.
Although, a new project can be created & run properly.
Kindly help...

Something is seriously wrong with either the project or the installation of VB6.
Are you sure the project was created in VB6?
Also from where did you install VB6 in the first place? Was it an original CD from Microsoft? Try uninstalling and then reinstalling (not a repair).

I have 1 application and I want to count it one time a day by using Proces Control, If user have run it for 30days the application not possible to use and Process Control is maximame
Please anyone know give a code

An easy way would be to write an installation date to the registry (or a hidden file somewhere on the hard drive) and then do a datediff function. If it returns < 30 then run regular code, if not, go to a form that shows how they can register. If you're going to do this tho, you should do some type of encryption of the date so your general user isn't changing the date every 30 days.

Can u give one example?
