[Pharo-dev] Enhancement - single operation revert to last saved image
Just a passing thought... as I am debugging, sometimes just before entering a step that I know is going to screw up the state of things, I save the image so that I can exit and restart to get back to that point. Now rather than having to manually quit restart, a command revert to last saved image which did the quit restart in one operation would be really nice. How doable would that be? cheers -ben

I would guess that you are already on the point of waiting for a server response, so you already successfully initialised networking, resolved DNS, opened a TCP socket and wrote the request over it. On the other hand, one of those steps might not have been done right, since you get no response. Any chance of a stack trace ? Or an image ? But that would be a headless one I guess ;-) Sven
[Pharo-dev] NB and ASMJit questions
Hi, I'm trying to mimic the following C/C++ example in NativeBoots to allow random number generation on windows: https://gist.github.com/kbjorklu/6317361 When I combine the flags in Pharo using | in the same way like in the first function call of the example: acquireContextExample1 NBFFICallout stdcall: #(BOOL CryptAcquireContextA(HCRYPTPROV self, 0, 0, PROV_RSA_FULL, CRYPT_VERIFYCONTEXT | CRYPT_SILENT)) module: #advapi32 I get an error 'comma expected'. Looks like the NBFnSpecParser does not allow expression evaluation like CRYPT_VERIFYCONTEXT | CRYPT_SILENT. Will this be possible in future versions? Nonetheless I tried to continue and since I defined: CRYPT_VERIFYCONTEXT := 16rF000. CRYPT_SILENT := 16r0040. I evaluated manually and tried to use the harcoded value directly: acquireContextExample2 Retrieves information about the current console font. primitive: 'primitiveNativeCall' module: 'NativeBoostPlugin' ^ NBFFICallout stdcall: #(BOOL CryptAcquireContextA(HCRYPTPROV self, 0, 0, PROV_RSA_FULL, 16rF040)) module: #advapi32 but this returns another error when converting using #asDWord: (16rF040 i4) exceeds doubleword (32bit) range in an AJImmediate but 16rF040. Looks like it is treated as unsiged since 16rF040 asUImm32 asDWord works. How to specifiy the number directly but as unsigned? To reproduce: - take a fresh Pharo3.0 Latest update: #30759 - load OSWindows from config browser to get the core and other packages - load OS-Windows-Cryptography package/mcz from smalltalkhub.com/#!/~OS/OS-Windows - evaluate WinCryptoProvider new acquireContextExample2 or WinCryptoProvider new acquireContextExample1 Any helping hand in converting the example would be appreciated.
