• Visual Studio how to find out current folder of imported file

• .NET Development Can a DateTime member for a generated DataTable be defaulted to Now?

  I have generated a strongly typed dataset for some tables in my database. For some of my DateTime fields, I would like to default them to DateTime.Now, but so far it's seeming that this isn't possible. If I try to enter "DateTime.Now" or some variation thereof in the DefaultValue field of the column properties in the dataset designer, it just gives me an error that the value is invalid (It seems to want a literal date value). I'm pretty much assuming that it can't be done, since in the database the field has a default value of GetDate(), and I assume if it were possible that value would have been included in the generated dataset a ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Effect file integration

  Just wondering how you guys integrate DX Effect files into your engines I see 2 possibilities A)For every effect there is a c++ class associated with it, with member functions for setting any effect specific paramaters (e.g. SetFrenselTerm()). B)A generic effect class that can load any .fx file and exposes its parameter via funcs like SetFloat, SetFloat4, SetMatrix, etc. A Pros: -Damn easy to implement and maintain -I can implement a fixed function class with the same interface, therefore not having to use a .fx file (if not needed) -Potentially very fast, we dont have to look up what function we have to call, or iterate A Cons: -Have to ...Show All

• Windows Forms Change the check mark color of a checkbox

  Hello, Is it possible to simply change the check mark color of a checkbox, either by programming or in the editor For instance, using the XP theme, I would like to have it red instead of green. Thanks, Monarghel Hi, I think there's no easy way of changing the check-color of a checkbox, because this require you to handle the paint event of the checkbox, then redraw the checkbox using the check-color of your choice. Your best option is to create a control derived from CheckBox control, then perform the custom drawing yourself. Regards, -chris ...Show All

• .NET Development How to measure the memory pressure?

  I am designing a .Net component that relies some on a quite elaborate cache system. The cache can be regenerated at any time but at great CPU/IO expense. The WeakReference is not enough my own needs because (for example) it cannot take into account the regeneration costs that may vary from a WeakReference to an other. I would like to know how the memory pressure that applies on the current process can be measured in .Net I have seen the method GC.GetTotalMemory() but the information brought by this method is partial.
