.NET Development insertion problem
i have a table in access2003 when a new record is inserted into the table(from windows appln) , variable counter should incremented by 1 now the problem is how to implement this and where to store the counter variable in database I believe you need to implement IDENITY field in your table and it will automatically increment on each new record. After record inserted, you could call SELECT SCOPE_IDENTITY() statement to get this value from SQL Server or SELECT @@IDENITY ina case of Access database ...Show All
Visual C++ VC2005 %50 Slower then VC2003
I just migrated a graphics application from VC2003 to VC2005. After building it, I ran a small benchmark & found that VC2005 code was about %50 slower. The Application does a great deal of floating point and integer calculations. It also converts doubles to int quite a bit (the VC2003 version used SSE to handle this). The VC2003 version used /G7 and /Ow (which are not available in VC2005) Compiler Switches Used: (vc2003)/arch:SSE2 /c /EHa /FD /GF /GL /Gs8192 /Gy /MT /nologo /O2 /Ob2 /Og /Oi /Ot /Ow /Oy /TP /W3 /WX /Zi (vc2005)/arch:SSE2 /c /EHa /FD /G7 /GF /GL /GS- /Gs8192 /Gy /MT /nologo /O2 /Ob2 /Og /Oi /Ot /Oy /TP ...Show All
Windows Forms Drawing an Image before the Text in a Custom DataGridViewTextBoxCell
Hi, I have a custom DataGridViewTextBoxCell. I need to paint an icon "prefixing" the Text. I tried overriding the Paint. And pushed the padding of the text. I have drawn my Icon in that space. But in this scenario my AutoSizeColumnsMode does not work. And the cell padding given for this cell makes the Header to be drawn with different width and the content cells to be drawn with different width. So, I would like to have a solution 1. Which allows me to put an Icon before the text. 2. Does not affect the AutoSizeColumns Mode functionality. 3. Keeps the cell resizing in sync with the Header Cell. Thanks in advanc ...Show All

Visual Basic MultiSelect List Boxes
I have created a form with three multi-select list boxes and hidden boxes to house the selections. I would like help with code that would allow me to sum each hidden box then multiply the sums by each other to get an answer when the "calculate" button is clicked Here's an example with 2 listboxes with objects loaded into each of them. When you click the button it will calculate the total of all the selected values in both listboxes. If you have databound items then you could total up the .SelectedValue properties. Hope this helps.

Visual Basic Listview Question
I have a listview that contains data that I'm pulling back from a database, which works great. Now I want to add a URL to the end of a description field, when certain criteria is meet, and that works. The problem that I have is that the URL is not clickable within the listview. Is there a setting I'm missing like the richtextbox detecturl's for the listview, or is there another way to recognize that text as a link so that I can do a onclick event Secondly, once I get the click working, I'll want to add an image rather than the URL in the listview, is it possible to load an icon sized image in the listview for the url ListView. ...Show All

Visual Studio Express Editions Cannot find add member variable wizard in class view
Hi, I'm in the class view window and have created a new class. I 'right click' on the class and expect to see the option: Add->member variable. In VC++ express, however, I see no option to add at all. Am I doing something really stupid, or is this not an 'option' in VC++ express. Apologies for such a dumb question, but I'd really appreciate some help.
