Hi, I have a problem while selecting between two dates. In my database "Kanservices.mdb" have a Date Column like 'DtTime'. It has both date as well as time. The above code is select between two dates.Its not working properly. If i store the Date in the DtTime column its working. If i store Store Date&Time the problem occurs.
Plz give the solution.
Thanks & Regards
Kumaran

Two words: "Parameterized Queries".
If you try and concatenate strings together, like you are in this code, you have to worry about putting the strings together with the correct date format. Using parameterized queries, the Parameters objects take care of that for you! You don't have to worry about getting the format right!

Hello,
I need help in my VB application.
I have a 'Browse' button in my application's properties page, which should help me to browse through the directory system to choose a directory to save the xml files into.
How to I get the directory system when I click on browse.
In C# we have the 'FolderBrowserDialog' , do we have something like that in VB.
Also how do I save files into the directory choosen by 'browse'
|
|
|
|
|
yes. In vb.net we have the same 'FolderBrowserDialog'.
you can use it for the folder selection.

I am not using VB.NET. My application is in plain VB. it is VB 6.0 from Visual Studio 6.0..
I tried to convert it to Visual Studio 2005, but then there were many other issues seen while running the application.
Can you please help me with something in VB

|

This is an enhancement to the already existing project. I want to enter a directory path to save some files. I want the user the choose the directory. For this I have introduced the 'Browse' button in the code.
But I dont know how the directory structure will be seen on clicking on Browse.
I tried just entered this line of code
' Dim theFolderBrowser As New FolderBrowserDialog '
and executed the application.
But on clicking on 'Browse' it said the User-defined variable is not supported.
How can I have the dirctory structure visible. I am using plain VB
|
|
|
|
|
after that
you can try like this...
for VS 2005
if theFolderBrowser.showdialog= Windows.Forms.DialogResult.OK Then
filename=theFolderBrowser.filename
end if
For VS 2003
if theFolderBrowser.showdialog= DialogResult.OK Then
filename=theFolderBrowser.filename
end if

I had another query
When I send the data to the server, the server forms an xml of the data and sends me the url to that xml.
Now, I am needed to save this xml into a particular directory(already known).
How to I read and save this file ?
I am not having a trace of the flow with me, so I dont have an idea how I will get the data in the xml and furthur will save it.
Can anyone help me to know how can I read the xml from the url to the xml and how do I save this file into a directory
|
|
|
|
|
you can try this
you know filename that is the url
you also know the directory path (savepath)
Dim xmlDoc As New XmlDocument
xmlDoc.Load(filename)
xmldoc.save(Savepath)
Sathesh Pandian
|
|
|
|
|
for the filename I will have to specify the whole path on the network system right ? I mean the xml will be on the server, so it will be
<serverip or="" name="">\<filepath>\<filename>
am I correct ?
|
|
|
|
|
is it physical path or virtual path?
if it is a valid path you can use tht link in the filename.
Sathesh Pandian
|
|
|
|
|
Sorry, What does a physical path or virtual path mean?
The server is expected to send something like 'www.server1.com\file.xml'
This is just an assumption, as we dont have the server implementation done and so cant get the actual packet trace.
|
|
|
|
|
ok you can use the load method like this
xmldoc.load("www.samples.com\1.xml")
no problem with this.

For better understanding, presently the server is responding with an URL pointing to the shopping cart which is then opened in the browser. These urls are in the form like
http://www.abc.com/
The application now wants the server to form xmls and send an URL pointing to the XML, back to the client.
I dont know how the client will get it back, I think it should be like
'www.server1.com\file.xml' or 'http://www.abc.com/file.xml'
Do you have any idea how it will be like. and Also the main point is that I should be able to save that xml file into the directory

you can try like this only
"http:\\www.samples.com\like.xml"

How do I check if a folder already exists on the system without including any classes?
I dont know why the Try-Catch block does not work in my code. It gives compilation error that try is not excepted

There is no FolderBrowserDialog in VB6. You have to make your own from scratch.
It's a bad idea to look at C# or VB.NET code and try to convert it to VB6. There is SO MUCH that the .NET Framework supplies, like the FolderBrowserDialog class, that you have to recreate from scratch that it makes using VB6 nearly impossible because of the time you'll waste reinventing everything you see C# and VB.NET using in the .NET Base Class Library.
