How can i do a workaround for this? I two databases(.sdf). Database A has table A1 Database B has table A2 Table A1 is an exact duplicate of A2 minus 3 columns My dataset(.xsd) is based off of tableA2 in Database B. I can fill all my tableadapters in Database A and all info in table A1 using the dataset. My problem lies when I do TableAdapter.Update() for Table A1(Since the dataset has the 3 missing fields) it tries to update table A1 with info that isn't there and I get an error. How can I update table A1 and ignore the 3 missing columns using the single dataset? Or is TableAdapter.Update() designed to Update the Database with all columns found in the dataset ?

View 4 RepliesSo I want to now if that possible for .NET languages to ignore error without using try catch construction ?
I can ignore warring with #nowarring 40 for example, can I ignore error ?
simply wanted to call system pause with this way
open System.Runtime.InteropServices
[<DllImport(@"msvcrt.dll")>]
extern void system(string str)
system "pause"
but got Error message
unbalanced stack. This is probably because the managed PInvoke signature does not match the unmanaged target signature. Make sure that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.
So I don't care, it works. But can I just ignore this error ? without doing weird stuff like that :
try (system "pause") catch |_->()
Ok , I solved my problem by adding CallingConvention=CallingConvention.Cdecl, but what the question was about skipping exceptions, so and I still don't know if I can do it.
So maybe I need to tell some real reason to not be down-voted hard - sometimes it's matters for program to live even with hard errors occupations, but even sometimes you don't need to catch them. You need just ignore them...
I use TortoiseSVN for versioning of my large VB Project in Visual Studio 2008. Once in a while, when editing one of the many typed DataSets, VS feels like switching the position of the attributes
msprop:Generator_ColumnVarNameInTableand msprop:Generator_ColumnPropNameInRow
In like nine THOUSAND places of the .xsd file. Sometimes I use a custom sed-script to reverse it again but most of the time I just commit it without knowing if there was any real change.
Can I prevent Visual Studio from messing with those attributes?
Can I enforce a specific ordering?
Or do I need some workflow within TSVN to ignore or revert such changes?
I wrote a small VB.Net Console app that scans thru the lines, sorting the attributes. It works on text alone as one cannot use xml parsing abilities without a massive increase in execution time and code size.
Does anybody know how to ignore a line(s) of code after a line(s) has executed. Let say you have a button1, and two CheckBoxes. By clicking once button1, cheheckbox1 checked. By clicking agin button1, then CheckBox2 checked. You will probably say that I can do that in diferent way, but it isn't the solution of this problem that I want. This is only an example.
