New API MetaTrader 4 AVAILABLE - page 18

Hello Tradezone,

I am interested in using your API, however, I am getting the same error as a previous post when attempting to logon,

System.Runtime.InteropServices.SEHException was unhandled
Message="External component has thrown an exception."
Source="WindowsApplication1"
ErrorCode=-2147467259
StackTrace:

I didn't notice a solution/resolution to the previous inquiry, has anyone faced this problem and fixed it?

Language being used is C#, via Visual Studio 2005, on windows vista.

Thanks

ADP.

No response...... bump, bump.....

Same problem in VS2008, however not a problem in VS2003???

VS2005 works when vshost is enabled, and run as administrator, otherwise does not, hence works in debugging, but not when deployed.

As far as I am aware, permissions are set correctly.

Can someone pls help with this problem its really p*ssing me off.

Hi Arlekind!

Yes, API supports more than one account in parallel.

HI ADPowers!

TZMT4API creates some working temp folders under <TZMT4API Folder>. If installation foler is under <Program Files>, vista will not allow folder creation.

Try to re-install TZMT4API in c:\TZMT4API, for example.

Youi must get a valid login.

Hi Tradezone,

'Youi must get a valid login.'

Yes I am aware of this fact, hence the probem/nature of my enquiry, Thanks for the suggestion, but unfortunately this doesn't seem to make any difference, see below.

There is no problem creating temp/working folders in the root directory of installation, whichever that may be (i have tried 3 now including c:/Program Files/Tradezone/TZMT4API as default installation path suggests, as well as c:/TZMT4API and c:/TradeZone/TZMT4API) as evidenced by the following screendump.

So therefore to eliminate access/securitiy issues to the tzmt4api.dll file in the system32 folder, so I tried moving the .dll out of the system32 folder and into the local working directory, ie c:\Tradezone\ and referencing it explicitly in the code, ie using [ DllImport ( @"c:\TradeZone\tzmt4api.dll" )] which gains a correct result from the VersionGet_MT4 function (therefore the .dll is recognised), but sill throws an SEHException when trying to log on.

But as mentioned previously, handle can be obtained under certain circumstances... which is perplexing.

As evidence of a successfull login attempt when vshost.exe is enabled in vs2005, see below (login details blotted out), as you can see, the handle value of '1' was assigned (refer to the mouse hover box) which is valid (-1 would have been assigned if invalid, and SEH exception not thrown)

To demonstrate what happens when the vshost.exe process is disabled, this is the output...

To clarify, when vshost.exe is enabled, the other functions seem to work fine, such as getting price quotes and acccount details, perfect, which leads to a possible solution direction, being, what is is that the debugger host is doing right which allows this to work, that a normal operating environment lacks causing error to be thrown? But im out of ideas...

Pls help me, I would really like to get this working.

Regards,

ADP.

Hi!

Are you using vista64 or 32?

If you are using vista64, under project's properties, go to build and force paltform target to x86.

Your project will be built in 32bits, same of TZMT4API.

There are some issues comunicating 64bit's process with 32bits.

Regards.

I am running 32 bit vista, see below.

Any other suggestions?

Hi!

We Are finding some issues mostly with security (license model). For this reason we are stopping to sell API until solve these issues.

Regards.

To: TradeZone

Would you inform me about conditions of selling the API (via email) when you resolve problems?

By the way:

If it is not secret, writing this software, did you only watch TCP protocol or decompile terminal.exe file? As I know this .exe file is encrypted against decompiling.

Do you maybe consider to write software to convert .ex4 file to .mq4?
