Can someone help me decode this HResult? What does it mean? I know the negative stands for a failure. How about the rest of the 10 bits?
I referenced MSDN HResult article here, but I am not sure how to determine what my facility and code bits are.
More info:
_message: "External component has thrown an exception."
Data: {System.Collections.ListDictionaryInternal}
I'll show you how to do it. Paste the negative number into Calculator (Windows) in programmer mode "Dec" setting. Then convert to "Hex" setting. You get the number: FFFFFFFF80004005. The error is 80004005 which is:
0x80004005
E_FAIL
Unspecified
Unfortunately the provider of the function that gave you this error did not categorize the error.
Useful links:
MSDN - HRESULT Format
MSDN - HRESULT Error List
Another way to do it is as follows. An HRESULT should contain a System Error Code in its first 32 bits. Using an AND operation will retrieve the error code from the HRESULT:
int result = (-2147467259 & 0xFFFF)
result is 16389, which is not a part of the System Error Codes list, and as a result, is unspecified.
Print it as an hexadecimal number, then, use for instance, VisualStudio ErrorLookup, to get the message.
-2147467259 in decimal is 80004005 in hexadecimal (usually rendered as 0x80004005). That's "E_FAIL (Unspecified error)" in Win32.
Not a very helpful error code, but maybe it'll get you a half-step closer to a solution.

I have a problem.
Firstly, There is a MSSQL Database and I sent to query with using PowerShell code. Then I take numbers from these tables (like U056258). After that, I want to mail the people have these numbers. But Powershell sends me an error. Like;
**Cannot convert value "U056258" to type "System.INT32". Error: "Input string was not in a correct format."**
**+CategoryInfo :InvalidArgument: (:) [], RuntimeException**
**+FullyQualifiedErorId :InvalidCastFromStringToInteger**
What is the "U" at the beginning ? Is it an unsigned number ? Remove it.
Ah, your ID isalphanumeric. Guy, don't cast into int32. Or remove the "U" before.
I got some account issues in the SCN so I make a attempt here.
We switched to Unicode and got some issues with that. INFTY_TAB = PS+2. This coding gets an error that "the offset + length is exceeding".
I found some hints but couldn't really figure out how to fix this. And even when I manage to fix those errors I got a new error called 'Iclude-Report %HR_P9002 not found'. The IT is still there so is there something else I can check?
Definition of PS:
DATA: BEGIN OF PS OCCURS 0.
*This indicates if a record was read with disabled authority check.
data: authc_disabled(1) type c.
DATA: TCLAS LIKE PSPAR-TCLAS.
INCLUDE STRUCTURE PRELP.
DATA: ACRCD LIKE SY-SUBRC.
DATA: END OF PS.
TCLAS is a char(1) field.
This is the part where the error pops up:
INFTY_TAB = PS+2.
Error: I had to translate so sorry for some mistakes that could appear.
Offset and Length (=2432) exceed the length of the character based beginning (=2430) of the structure.
Depends on the length of INFTY_TAB. You have to explicitly set length:
INFTY_TAB = PS+2(length).
Official information is here. The important point to note is that the inclusion of SY-SUBRC (which is an INT4 field) places a limit to the range of fields you can access using this (discouraged) method of access.
ASSIGN field+off TO is generally forbidden from a syntactical
point of view since any offset <> 0 would cause the range to be
exceeded.
Although the sentence above is related to ASSIGN command, it is also valid for this situation.
I program with libpq.so. I want to get the error code which is called sql state in SQL Standard.How should I get this in my c code?
The obvious Google search for libpq get sqlstate finds the libpq-exec documentation. Searching that for SQLSTATE finds PG_DIAG_SQLSTATE in the PQresultErrorField section.
Thus, you can see that you can call PQresultErrorField(thePgResult, PG_DIAG_SQLSTATE) to get the SQLSTATE.
This is just addition I can not leave in form of comment due to reputation reasons.
Note that you can not portably get SQLSTATE for errors that can occur during PQconnectdb. In theory, you can read pg_conn (internal struct) field last_sqlstate which contains correct value.
For example, if you try to connect with invalid login/password, it will give you 28P01. For wrong database it will contain 3D000.
I wish they defined publically available getter for this field.

I have my java program connected to postgresql. I want to retrieve the error codes for sqlexception. I found the error code for postgresql here.
But Java's SQLException contains only methods for error codes returned as int getErrorCode()
But the error codes in the link are not of the type int. Where can I get the int error codes for postgresql?`
I think that getSQLState() is what you are looking for:

I'm trying to analyze how postgreSQL parse a query, and after some postgreSQL source code tracing with embedding printf() here and there, I've known that the query will be parsed into raw parse tree with raw_parser, which located in file parser.c.
The strange thing is, I've already embedded a printf() dummy in the raw_parser, and after re-installing the postgreSQL and execute a query, my printf() dummy is not printed to the screen!
Can anybody please help me, where I went wrong?
Thanks in advance :D
if you use printf(stderr, "...."), then you can find result in server log. Don't forget - you are not work with server directly. For debugging purposes there are a elog function - it's like printf for client application:
elog(NOTICE, "some text");
a format string is same like printf's format - but you must to remember, PostgreSQL uses a different formats than glibc - so you can to show only integer or float variables. String variables uses different format than is C zero finished string.
