FannwongCindy Web.Config
Hi there, I have used the sample website which is already made for you (With Web.Config) when you load it in visual web developer but after I upload the whole website to the web.

GrandpaB GetChanges() always returns null table
I have a database with two tables. ContactInfo (Contact ID int (PK), Last Name varchar(50)) AltAddress (AltAddressID int (PK), Address varchar(50), ContactID (FK)) I'm wanting to display and update related in text boxes on a form. Each ContactInfo entry will only have one AltAddress entry. I've added the text boxes from the DataSources windows and it creates two Binding Source objects. ContactInfoBindingSource(dataSource = testDataSet, dataMember = ContactInfo); AlternateAddressBindingSource(dataSource = contactInfoBindingSource, dataMember = altAddressContactID_fk) This works for displaying the data correctly! My problem is when I try to get changes to the altAddressTable, it always returns a null table. Here is the line ...Show All
joss1974 XmlValidatingReader does not give any validation error
Hi I am using XmlValidatingReader to validate my XML with schema. There is a particular validation error that does not appear when I use the XMLValidatingReader, but it is shown when I try with XML SPY.

allpdoff How to use pointer to "ref class Form1 : public System::Windows::Forms::Form"?
I pass the the pointer of ref class Form1 to an non-ref object. (It has to be non-ref as it derives from generic code that has to work on non-.NET platforms, as well). E.g: System::Void Form1::insertToolStripItem_Click(System::Object^ sender, System::EventArgs^ e){ //Display is global object Display.Event_Insert( this ); } The pointer is then used to create graphics. E.g: void SNetDisplay::Event_Insert(System::Windows::Forms::Form^ const aDisplayForm){ // iDisplayForm is of System::Windows::Forms::Form^ const * type iDisplayForm = &aDisplayForm; Graphics^ g = (*iDisplayForm)->CreateGraphics(); ...

Venkata Bayanaboyna Architecture issue similiar to Device.IsHandlingEvents
As we all know there're some issues with Device.IsHandlingEvents, so we usually set it to false at the first line of our code. I'm writing a small graphics engine and I'm facing a similiar issue: If I want to hide the device lost/reset housekeeping job, my object must handle these events from the d3d device. But if my object handles these events, the d3d device will hold a reference to my object, that means it won't be garbage collected as long as d3d device lives. So the finalizer fails to be a safe-guard in case Dispose() is not called. I currently have 3 ideas: 1) Keep it that way and make sure the user calls Dispose()...sounds quite prone to memory/resource leak. 2) Expose OnDeviceLost()/OnDeviceLost() like D3DX objects. .. ...Show All

I found a bug when I am programing: when I use like this: " ".IndexOf(" ") is returns -1,when it should return 9; but " ".IndexOf(' ') is OK. and belows all worked well: " ".IndexOf(" "); " ".IndexOf(" "); " ".IndexOf(" "); My environment is : Windows XP SP2(English Edition + Mutil-Language Pack) + .NET Framework v2.0.50727+Visual Studio 2005 PS: It works well in javascript. I understand your examples with double quotes all around. The thing is here more about simple quotes versus double quotes. Do you mean that the character between simple quotes is not unicode Why would the search work for it with simple quotes and not double quotes...... Actually, it is entir ...Show All
Hikmer xsd.exe fails to create common data types out of nested schemas
Hi, with the contract first approach we have some xsd schemas as the core interface definitions. We outsourced common data types (enumerations and some length limited string types) in a shared common.xsd file which in turn is <import> ed into the top level xsd schemas. We tried to generate .cs code files with xsd.exe in this scenario. But all the generated code files repeatingly contain the common data type definitions. This leads into several compiler errors. Using different namespace delcarations for each generated class does not solve the problem: The shared character of our common data types is completely lost after code generation with xsd.exe ! It seems to be a popular problem, because shared data types is a commonly u ...Show All
