What specific error are you getting when the app falls over?

When my app fills a table adapter with values, null values go in just fine. Doesn't matter what types the values are. But, in a separate operation, when I try to insert a row, I get null value exceptions, even for the values declared as NULLABLE. I guess I need to test each value by using .hasValue, but what I don't understand is why the fill works with no problem and the insert doesn't.

Hi Ken,
First of all, you probably mean that your app fills a DataSet with the use of an adapter.
Something like MyAdapter.Fill(MyDataset). The DataSet aparently is set to ignore restraints, so the fill operation, which is basically nothing more than a read operation, works just fine. When you use your adapter's InsertStatement, you actually tell it to create new data in the source table (database). All therefore depends on the design of the table in your data source (database?), from its properties you can see which fields must receive a value.
Hope this helps,
Johan
My advice is free, and you may get what you paid for.

Johan, thanks for your clear explanation. Based on what you have pointed out, looks like I need to look more closely at the settings of the Access database that I am using--Ken

Please don't cross post. Are you doing this in C# or VB.NET ?

hello frnd,
do u want to open the already saved file if yes try the following
first add the COM reference, if you have word 2000 then add
microsoft word object library 9.0 and if you have word 2003 then do add microsoft word object library 11.0
and then code as,
imports word = microsoft.office.interop.word
dim objApp as new word.application
dim objDoc as new word.document
objDoc = objApp.documents.open("\\Address Of Blank Word File")
objdoc.visible = true
and after writing content to file the user close the file
By this code ; Already stored file open and displayed
AND If you want to open the new file then
dim objApp as new word.application
dim objDoc as new word.document
objDoc = objApp.documents.add("\\Address Of Blank Word File where u want to create")
objdoc.visible = true
in both the case the user must write and save the document

hello guys
I have the following code:
Dim lineArray As String() = ProcessBuffer.ToString.Split(ControlChars.Cr)
Dim lineArrayList As ArrayList = ArrayList.Adapter(lineArray)
I use the Adapter method to convert my array to an arraylist, what is far more easy to work in my program.
Now when i want to remove a index I get this exception.
Unhandled Exception: System.NotSupportedException: Collection was of a fixed size.
at System.Array.System.Collections.IList.RemoveAt(Int32 index)
at System.Collections.IListWrapper.RemoveAt(Int32 index)
Anyone an idea how to avoid this problem without using a manual copy of all the elements into the arraylist. Because it seems that the arraylist gets a fixed size. :-/
|
|
|
|
|
try using the ArrayList(ICollection) constructor, that one copies the items for you.
|
|
|
|
|
Thanks for the answer.
I was checking ArrayList(ICollection) and I can't figure it out how it works, what i do, the same problem appears. Can you help me by putting me in the right direction?
Thanks.

Hi,
this is C# code that works; it prints 5 and 6
ArrayList list;
int[] arr=new int[]{1,2,3,4,5};
list=new ArrayList(arr);
log("count="+list.Count);
list.Add(6);
log("count="+list.Count);
If I am not mistaken, the crucial line translates to VB.NET as:
list=New ArrayList(arr)

Thanks that does the job. Now I can delete what I want without having problems.

Your question doesn't make a whole lot of sense. You can draw anything you like on your forms. Where do you want to draw it ?

think he want it to orbit around his form, passing in front and behind, maybe direct him to the graphics forum.
