As I can't use these components because the sovket reception opens a new thread I have to use a new thread an fix the ApartmentState to STA. Inside this new thread I declare objects from this dll and if I open the task manager of windows I can see that the size in memory of the proccess increases a lot every time a new message is received. I thought that the garbage recollector should make it for me but how can I free resources? I'll try to set the objects to null but I don't know if this is the best solution (if it works,obviously). Thanks in advance.

I want to create a folder and assign a icon to the folder I created so that the folder does not show a generic icon. directory.create(...) will create the folder but I do not know in code how to assign a icon? In windows I just change the folder to a system folder and modify the desktop.ini file. Re: Place an ICON on a folder?

After a press of a button, on next page a table is generated, and it fills with numbers using ajax. So at the start table cells have this rotating gif "saying" that data is being collected, and after some time numbers appears. So my question is how to get the source of the page AFTER all ajax events is being finished? I have tried to use this method, and I had some strange results - one day it worked, next day it won't. So, maybe there's another examples? Thanks!

Re: Conervsion formula for XY coordinates of Picture Box to Lat/Long stancrm30-Aug-09 22:48 stancrm 30-Aug-09 22:48  First of all, you must know how to convert degree,minute,second to decimal and vice versa... The next step, you must know, how big is your image (for example : 1000x1000 pixel) Then you must know, which coordinate is the left, right, top and bottom side. For example : Image is X = 1000 pixel Y = 1000 pixel Left = 0° Right = 10° Top = 0° Bottom = 10° That means horizontal at pixel 500 is (500*10)/1000 = 5° and vertical pixel 300 is (300*10)/1000 = 3° and so on... Re: Conervsion formula for XY coordinates of Picture Box to Lat/Long kjsl2k931-Aug-09 1:09 kjsl2k9 31-Aug-09 1:09  Hi, I had used the formula for calculating the Lat and Long by first calculating the dX and dY and then applying the following formula : - public point XYtoLatLong(float X, float Y) { float Lat = LAT0 + dY * Y ; float Long = LONG0 + dX * X ; point pnt = new point(X, Y, Lat, Long); return pnt; } where X and Y are the points of the picture box where the mouse is moved , Lat0 and Long0 are calulated as : - delX = (maxLONG().LONG - minLONG().LONG) / (maxLONG().X - minLONG().X); delY = (minLAT().LAT - maxLAT().LAT) / (minLAT().Y - maxLAT().Y); lat0 = maxLAT().LAT - maxLAT().Y * dY; long0 = minLONG().LONG - minLONG().X * dX; maxLat and maxLong are used for getting the maximum Lat and Long but the Lat and Long I am getting is giving the error of -0.00478 in Lat and +0.00389 in Long.How can I remove the Error. Thanks Hi peoples Hema Bairavan30-Aug-09 18:54 Hema Bairavan 30-Aug-09 18:54  i have one doubt, actually i have declared a string array string ex = new string[3]; in a method i m returning string[10]. ie private string temp() { string temp1 = new string[10]; } ex= temp(); before calling this method my string ex size is 3, but after calling the method it size increased to 10.. is it possible how come?? actually at the starting itself we have allocated the memory as 3, how its getting increased?? can any one help me?
