• .NET Development Requests and responses use the same port number (80)?

  Hi,  If I send out 10 concurrent/simultaneous requests from a client to a web service, will the web service process the requests and send out the responses through the same port number (80), or different port number for different request What I observed is, IIS is using the same port number (80) to send out the response. Well, in this way, the problem is, won't this shared port be a bottleneck for the web service For example, I am sending 10 concurrent/simultaneous requests from a client to a web service. And the web service will send back the file specified by each request. If they all go through the same port, these 1 ...Show All

• Visual Studio Print Preview Problems and Two Questions

  I'm having problems with Print Preview on a LocalReport. The "Generating Report" message stays on screen even after the toolbar becomes re-enabled. I can print, via the print button, refresh, and go back to the normal view. However, the problem does not occur with the sample Web Log Analyzer project. I have deleted the report and recreated it (several times). The only thing I haven't done is to compare the XML of my report and the Web Log report to see if there is anything radically different. The report is a LocalReport (embedded resource), using A4 page size and 1cm margins. The data supplied is via 4 business object types. 3 are supplied ...Show All

• Visual C++ The debugger isn't displaying std::wstring values

  I have tried to use an std::set<std::wstring>, and the debugger appears to have a problem with displaying the values that are stored in the set (this also happens when using std::wstring as the key value in a map. Sample code: #include <set> #include <string> int main() { std::set<std::wstring> test; test.insert( L "1234567" ); // this is displaying correctly in the watch window test.insert( L "12345678" ); // this is displaying garbage in the watch window return 0; } This isn't a major problem, but makes it more difficult to use std::wstring. ...Show All

• Windows Forms Update Needed?

  Here is a simple question, but I do not find the answer anywhere else: How can I check if the data in my dataGridView has changed I want to ask confirmation from the user before I update the TableAdapter. Thank you.     If you are bound to a DataTable in a DataSet, DataSet has a HasChanges method. If you are bound to a DataTable, you have to iterate through the rows in the DataTable and check the RowState of each for something other than unchanged. If you are bound to a custom object, it will have to provide a way for you to detect changes. The point is that you dont detect changes thro ...Show All
