Re: [Help-glpk] Help! AccessViolationException in GLPK
Hello!
I try use glpk for c#.
I'm widows 10 and VS 2015 amd 64-bit Windows. But my application is 32 bit.
I add libglpk-cli.dll to project and add libglpk_cli_native and glpk_4_60 to
/bin directory.
Test to solve was excellent.
When I try use glpk in me application
In GLPK.glp_add_cols(lp, varcounter), when varcounter= big number, for example
varcounter=4961
I get exception
'GLPK.glp_add_cols(lp, varcounter)' threw an exception of type
'System.AccessViolationException'
Data: {System.Collections.ListDictionaryInternal}
HResult: -2147467261
HelpLink: null
InnerException: null
Message: "Attempted to read or write protected memory. This is often an
indication that other memory is corrupt."
Source: "libglpk-cli"
StackTrace: " at org.gnu.glpk.GLPKPINVOKE.glp_add_cols(HandleRef jarg1,
Int32 jarg2)\r\n at org.gnu.glpk.GLPK.glp_add_cols(glp_prob P, Int32 ncs)"
TargetSite: {Int32 glp_add_cols(System.Runtime.InteropServices.HandleRef,
Int32)}
Help me, please!

Re: [Help-glpk] Help! AccessViolationException in GLPK
Hello Natalia,
indexes in GÖPK start stopp 1.
So if you have 10 rows/columns you need arrays with 11 entries.

Re: [Help-glpk] Help! AccessViolationException in GLPK
Thank you!
I understand that, and create a variable with the number 1.
The problem occurs at 4965 variable. And this is not the last variable. And
each time is a different number.
while (dateFrom <= dateTo)
{
for (var hour = 0; hour < 24; hour++)
{
var paramDate =
station.Compound.GetParamForDate(dateFrom);
var paramHour = paramDate.ParamByHour(hour);
varCounter++;
paramHour.PriznakDozagruzki = new
PriznakDozagruzki()
{
ParamType = TipDozagruzki.Pmax,
Day = dateFrom,
Hour = hour,
Position = varCounter,
StationID = station.ID
};
taskGLPK.AddVariable(varCounter, lp, GLPK.GLP_BV);
station.FuelInfo.ToList()
.ForEach(p =>
{
varCounter++;
var b = new RashodTopliva()
{
Day = dateFrom,
Hour = hour,
Position = varCounter,
Station = station,
FuelInfo = p,
};
p.RashodTopliva.Add(b);
taskGLPK.AddVariable(varCounter, lp,
GLPK.GLP_CV);
});
}
dateFrom = dateFrom.AddDays(1);
}
public void AddVariable(int varcounter, glp_prob lp, int type)
{
GLPK.glp_add_cols(lp, varcounter);
GLPK.glp_set_col_kind(lp, varcounter, type);
}
