I need to have some of my columns in an integer value not string.So from I can tell so far and I am extremely limited, if I use WriteXml this should write the schema and the data and the readxml will read the schema and the data, although I dont see the schema in my xml file that gets created from my oDS.WriteXml/if I use oDs.WriteSchema I can view the schema file that is created. Thats how I determined the schema is creating all string vlaues for each column..All the fields are of String value as was pointed out, so how do i create my own schema file? or rewrite the one that is created.[code]
View 5 RepliesI am having a problem with my program that is desinged to read a 3rd party text file database. I posted previosuly about a problem inserting an item in a new row and the column was expectig a different data type. It appears that sometimes the column is being determined to be of decimal value, I dont understand why. the fields contain information such as
Col1
F123456
CLW-12321 etc....
So my column fills with
123456
12321 the letters just get chopped off
So I added MaxScanRows = 0 to my schema file and that took care of the problem
Except now several of my columns that contain Date Values are coming back
9/24/2010 00:00:00
without the setting MaxScanRows = 0
The date returned 9/24/2010
Here is the code for my schema ini file I am creating:
HTML
Dim fs As New FileStream("Schema.ini", FileMode.Create, FileAccess.Write)
Dim writer As New StreamWriter(fs)
[CODE]............
I have been trying different settings hence the dimmed out lines
Here is the code to fill the datatable:
HTML
[CODE].............
I am thinking that without the MaxScanRows = 0 setting the datatype for Col1 is being incorrectly determined
I am not sure what is happening with other columns that contain date values. Apparently If i use MaxScan Rows=0 all columns are being pulled over as string value which creates numerous problems. If I dont use maxscanrows then all columns appear to be correct except Col21 MLSNUM which is being pulled in as a decimal. Can I change that in the schema file?
A similar question has been asked before but noone seems to have an answer.I have an xsd which is fairly complex in nature.I must now create the xml file to be validated against it but I hate trying to interpret xsd. It's all gobbldygook to me.
Is there any way I can take an xsd file and create on the fly an example of what the xml file should look like?
I have had a problem with my program not working on a windows 7 machines so i finally built a box with Windows7 to test it.

I'm developing a VB Web Application in .NET3.5 using Visual Studio 2008. I'm having difficulty in validating some XML as a string before I add it to a HTML form to post to a 3rd party. I have an XML schema file from the 3rd party to validate against and at this point I'd like the application to perform the validation before each post.
After searching I've found references to a XmlValidatingReader but this is obsolete and I'm having difficulty finding another way to do it. Also all the good examples are in C# - for now I'm stuck with VB. This is what I have so far which I'm looking for with! Public Function ValidateXML(ByVal strXML As String) As Boolean

I have created an xml schema and an xml file from a datatable. I am now trying to read that data in which is working fine. I can access the data but the problem is that I want to know how many Tables there are in the xml file. For example the setup looks like this: [code] I want to know how many "<table>" objects there are.
View 2 RepliesI have an untyped-Dataset with two related DataTables, and I have a grid bound to the parent DataTable. I used the WriteXMLSchema() method of the parent DataTable in order to save the schema in a xml file. Then I opened the file with the Notepad, deleted two columns from the schema file and saved it. After that, I used the ReadXMLSchema() of this DataTable but -contrary to what I would have thought- the DataTable's structure was unchanged. Using the debugger I noticed that after calling the method the number of columns was the same. Why? How can I make the DataTable's schema to be changed by using a file?
notice that I am using the DataTable's methods and not the Dataset's because I do not want to touch the child DataTable.
I have written an import routine, that imports a textfile into a database table, using a schema.ini.In the input file, 3 fields are seperated, that should be concatenated in the import-routine. Does anyone know how I can make that happen...Small part of the import-routine, first lines are the last lines of the programatically created schema.ini.

i have been coding for years, but never integrated XML. So I guess I'm a newbie. I have inserted an XSD file in my project, ARequest.xsd. I created a folder in my project called XML just to organize things, so this file ARequest.xsd, is in this folder.
Now I have a form that displays data from a database that has the same fields that are in this XSD file. Can I load the XSD file into my Windows Form, load the elements from the data on the windows form and then create an XML file then send it? If so how? Any code snippets would be helpful. Now I do know how to create the XML file, we'll call it Test as

I have an .XSD that is made from a class so that I can pass to a webservice. It got it over to the webservice as an XMLSchema object and now I need to make it into a class so that I can make objects out of it on the webservice side. I know that XSD.exe is the answer but I'll be darned if I can puzzle out exactly how to implement this thing. I need it to do this conversion at run time so I need to put the code for it into my project and all the references I've seen to using XSD.exe talk about calling it from the command line.

There is an old timesheet application being used in my company and i am going to rewrite it in asp.net.There are other tables which can be linked to new Timesheet table like employee table but my main concern here is the Project and Project_Activity table.In the current system, there is a one project and a activity table which are linked to the timesheet table seperatly and user has to spend alot of time on selecting activities code they worked on for specific project.I have came up with the new idea; Project manager will have to fill up a project template and link all the activities code with the one project before starting this project. This way user will have to select the project only and it will automatically bring the associate codes for them.I like to know if this design will work okay? and is it okay to link Project_Activity table with timesheet?
