leak of system resources. Carefuly explore your's (written by you or your colleagues) and 3rd party control's classes (TGraphicControl, TWinControl, TControl), find the places where resources acquired and check them to be properly released after use (use 'try..finally..end'). Search in Paint(), CustomDraw() etc. methods of controls and forms. Search for "TIcon", "TBitmap" .Create/.Free, for Windows GDI resources usage ("THandle", "HDC", "HIcon", "HCursor" etc.). And search other Windows API functions, used in your application, the results of which must be finalized, but, in fact, are not finalized in your code.

Posted on 2003-07-18 Delphi 4 Verified http://community.embarcadero.com/answers/out-of-system-resources Solutions 26 Comments 6,157 Views Last Modified: 2007-12-19 Hi, We have our big application contains lots of forms. I should tell a brief background of it. We have created a user-interface in Delphi 5 for Cobol applications. It is a single big DLL for GUI for our application. This DLL is using Transoft ODBC to connect to the database, and besides https://www.experts-exchange.com/questions/20683441/Getting-System-Out-Of-Resources-EOutOfResources-error.html an Acuconnect tool is being used to enable the cobol program to work with GUI interface. I have built a process which has a loop to run some screens automatically by clicking appropriate buttons in the background while a form is stay on top tells the process progress. During this process, usually delphi generates an error "System out of resources." (EOutofResources) when it tries to open a requested screen. I have been reading here regarding this error, so I have tried some changes as well like not to autocreate forms, and also I think I release/free forms properly when they need to be closed. Anyway, during this error, I got another error like "Too many open files.". We are not using lots of bitmaps and graphic files. I have tried to reduce number of unnecessary controls from the form, but it did not help. Please anybody could give suggestions to resolve this issue. I tried replacing Free/Release method but it did not solve. Following is a piece of code if it could help you to understand. This code is trying to ope

when it comes to freeing memory and resources. Although Delphi has a powerful mechanism of safeguarding the allocation and deallocation of memory and resources using a try-finally block, it's still up to the programming to do so. And in case you forget to deallocate a component, you'll lose memory and especially resources fast. How can we be sure our applications don't leak? We need a resource monitor, to watch things behind our back, and report the percentage of free resources to us. In this article, we'll design and implement a simple resource monitor that will be able to assist us in watching resource and memory leaks. Free Resources Windows itself can tell us how much resources are available (in percentages). The Windows 3.1 API function GetFreeSystemResources returns the percentage of free space for system resources. The declaration of the function is as follows: function GetFreeSystemResources(SysResource: Word): Word; Where the SysResource parameter specifies the type of resource to be checked: GFSR_SYSTEMRESOURCES for the percentage of free space for system resources; GFSR_GDIRESOURCES for the percentage of free space for GDI resources (device-context handles, brushes, pens, regions, fonts, and bitmaps) or GFSR_USERRESOURCES for the percentage of free space for USER resources (window and menu handles). Free Memory In contrast to Windows Resources, we can ask Delphi how much memory is has available for our application. Like Turbo and Borland Pascal, this can be done using the MemAvail function from the system unit. Note that MemAvail does return the total amount of available memory, which is not necessary in one continuous block. If you need to know the biggest block of available memory, you should call MaxAvail instead. Finally, it is important to know the amount of free memory below the 1Mbytes. This amount of free memory is needed for every executed Windows application, which explains why you can get the message "Insufficient memory to run application" on a 16Mb Pentium that says you have over 12Mb of memory and 60% of resources left.
