I'm looking for some code in .net to allow me to test an xml file to determine if it is well-formed. I am not validating the file against a schema at this point in my code, just testing that it conforms to xml specification for being well formed.

I am trying to get the path for my page and I succeed to get it using an HTML image tag:
<img src="images/slider/<%# Eval("BannerImage") %>.jpg" alt="" />
Is there a way to make it dynamic using the asp:Image tag?
I tried to make it like this:
<asp:Image ID="Image1" runat="server" ImageUrl="~/Classified/Images/Slider/'<%# Eval("BannerImage") %>'.jpg" />
And I got an error:
The server tag is not well formed.
I want to build a small project which uses XML literals I want to create an XML document,store it and then use the project to open it and make changes to it (i.e. add nodes etc).When I do this I want to have a control on the left which illustrates the property formed XML and on the right a DataGridView control which I wil use to import the XML data. I want the abilty to see in realtime the changes I make to the XML and how it looks in the DataGridView. I will make changes using buttons on the form.So really the purpose of the project is to show what the actual XML looks like and what it will look like when I import it into a DataGridView.
View 7 RepliesThere are samples of Runtime copying things, But what I want to do is: Copying a panel formed in the desining level (with the controls on it)The name of the panel formed on Form1 is PanelTaslak:Dim Panel1 as Object

Panel1=PanelTaslak is considered as when I write Panel1=PanelTaslak
Panel1 takes the place of PanelTaslak

I am building an application to update a database.I have a Map table where row 0 holds the target table field name Row 1 holds an update value or Source table Column name Row 2 holds a Where condition eg
Map: CustNo CustName Val1 Val2
Update: 25
Where: =[CustNo] > [Fld14]
In this example I am going to update the Target Table Field 'Val1' to 25 where the Target Table Rows have Field 'Val1' data > 14 AND Target Table Field 'CustNo' = the Source Table Field 'CustNo' AND the Target Table Field 'Val1' > the Source Table Field 'Fld14' Where I am stuck is I at the moment is wondering how I should convert the strings into test conditions as I iterate the Target Table eg Say my test string is stTest and it holds " = 25" For each dr as datarow in dtTarget
some code
... stFld = "Val1"
if dr(stFld) { convert stTest into literal '=' and then 25}
... do something the only way I can think is to build up a series of test cases like:
Select stOp
Case stOp = "="
Case stOp = "<>"
etc.

I have two tables, dt & dtResults.dt contains 3 columns named: vchInstrumentAnalyteID, bintAnalyteCodeID, & vchAnalyteCode dtResults contains several columns including the columns in dt
I want to get vchInstrumentAnalyteID from the first row in dt and test if it exists in the vchInstrumentAnalyteID column in dtResults. If it exists, I want to use that value from dt to filter rows in dtResults and fill all the filtered rows with data from that row in dt. Then loop to the next row in dt.

I want to test whether the connection string is valid or not?What should I do ?
View 18 RepliesI need to test a string of text that needs to contain a certain type of char values. The known is allowing of a-z,A-Z,0-9. But the variable (which will be coming from a database field) will be the allowed symbols. The allowed symbols will look something like:!@#$%^&*()
So using regex, how can I check a string of text to make sure it ONLY contains a-z,A-Z,0-9 AND the allowed symbols as shown above? Remember, the allowed symbols is dynamic at run time so I need to somehow be able to plug that in to the method at run time.
The following examples would be valid using the above symbol string:
Test1234%
Test1234
The following example would NOT be valid:Test1234%_
I've set up a test database to begin unit-testing an app that I've recently been added to. It is a 3-tier design (presentation layer, BOL and DAL) and this is my first time writing unit tests. I've decided to start at the BOL and I figure the best way is to swap out the ConnectionString (which has been passed along as a Shared String) with one that points to my new test database. However, I don't wish to change any production code. I simply wish to somehow redirect the app to the test database during unit tests.
View 4 RepliesI have the following query
Dim get_rmf_2 = From rmf In t_rmf _
Where rmf!NIVP = nivp_rap
When i run it i get an error :
Operator '=' is not defined for type 'DBNull' and string "test".
I suspect this is because the column "NIVP" in the datatable contains null values, I've tried yhe same thing without null values and it works.So how can i make this work ? ; the column "NIVP" really has a row "test" , and a normal SQL query works fine.

Probably a dumb question, but can you write a unit test project in one language to test against another project in a different language?I'd like to translate one of our VB assemblies into C#, but want to build unit tests to verify the results. I've tried to set a unit test project up to do this, but I can't seem to access the VB code within a unit test... I can't figure out if I'm just missing/doing something stupid, or it really isn't allowed.

I have a large VB/SQL application that I have created a problem in. I have a table of procedures that have an active flag on them. This flag can be toggled through a user screen. Other screens access this same table to populate dropdowns. The values are stored in the table as the ID field (PK). The problem I have is that I am selecting the dropdown values based on the Active flag. If I select a record that has a procedure stored in it that has been made inactive, I get the old Object Not Set to an Instance.... error.
What I want to be able to do is check for the value in the record when populating the dropdown and allow the record to be displayed by bypassing the SQL error and just showing the dropdown value as blank while not altering the record itself. I hope I'm making sense. Code is below.but I'm back in app programming after being a SysAdmin for 20 years and I'm still rusty.[code...]
If the condition = true How do i select all records stored in .txt (temporary text file) to be updated in sql table How do i do that.
