Anyone, any suggestion? Thanks,

  • Strange error with CreateCompatibleDC

    - by sevaxx
    Maybe this is a foolish question, I can't see why I can not get a DC created in the following code : HBITMAP COcrDlg::LoadClippedBitmap(LPCTSTR pathName,UINT maxWidth,UINT maxHeight) { HBITMAP hBmp = (HBITMAP)::LoadImage(NULL, pathName, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_CREATEDIBSECTION); if (!hBmp) return NULL; HDC hdc = (HDC)GetDC(); HDC hdcMem = CreateCompatibleDC(hdc); if (!hdcMem) { DWORD err = GetLastError(); } ... ... ... The bitmap hBmp is loaded fine and hdc has a valid value. But the call to CreateCompatibleDC() returns a NULL pointer. Then, GetLastError() returns 0 ! Anybody can guess what's going on here , please ? PS : There are no memory allocations or GDI routines called before this one...so I think memory leaks should be ruled out.

  • JFreeChart Ugly Rounding Error?

    - by billynomates
    Using series.add(180, 1); produces a perfectly valid chart like this (little red dot at the bottom with some PolarItemRenderer Mods!) but using series.add(3000/(6000/360), 1); produces this beast: I assume it's because somewhere, 6000/360 = 16.6... is getting rounded? How can I stop this happening? Thanks :)

  • SQL decimal conversion error

    - by jakesankey
    Hey, my app parses numerous txt files in a directory that are almost all formatted identically, then inserts the values into columns of my sql db. However, there are a few files that the app has come across where a value is 'blank' instead of '0.0', so the application fails stating that it cannot convert that value to numeric. Is there a way I could change the following code to say what says AND also add 'IF value is blank, then import 0.0 instead? foreach (SqlParameter parameter in insertCommand.Parameters) { parameter.Value = null; } string[] values = line.Split(new[] { ',' }); for (int i = 0; i < values.Length - 1; i++) { // if (i = "" || i = null) continue; SqlParameter param = insertCommand.Parameters[i]; if (param.DbType == DbType.Decimal) { decimal value; param.Value = decimal.TryParse(values[i], out value) ? value : 0; } else { param.Value = values[i]; } }

  • "lock request time out period exceeded" Error When Trying to See DB Hierarchies

    - by Lloyd Banks
    I have a DB that I can run basic queries (albeit much slower than normal) off of. When I try to see the hierarchy trees for tables, views, or procedures in SSMS Object Explorer, I get the "lock request time out period exceeded". My Report Server reports that run off of objects in this DB are no longer completing. Jobs associated with procedures stored on this DB also do not run. I tried using sp_who2 to find and kill all connections on the DB. This has not solved the problem. What is going on here? How can I resolve this?

  • Error in qsort function in Programming Pearls?

    - by Dervin Thunk
    Hello, is it just me or this code in Programming Pearls is wrong (quicksort wants 2 const voids, no?) If so, is my solution right? Apologies, just learning... int wordncmp(char *p, char* q) { int n = k; for ( ; *p == *q; p++, q++) if (*p == 0 && --n == 0) return 0; return *p - *q; } int sortcmp(char **p, char **q) { return wordncmp(*p, *q); } ... qsort(word, nword, sizeof(word[0]), sortcmp); Is this a solution? int sortcmp(const void *p, const void *q) { return wordncmp(* (char * const *) p, * (char * const *) q); }

  • What is the Action returned by the subscribe parameter of IObservable.Create actually for?

    - by James Hay
    The method definition of IObservable.Create is: public static IObservable<TSource> Create<TSource>( Func<IObserver<TSource>, Action> subscribe ) I get that the function is called once the observable is subscribed to, where by I can then call OnNext, OnError and OnComplete on the observer. But why do I need to return an Action from the subscibe parameter and when will it actually be called?

  • Make a usable Join relationship with LINQ on top of a database CSV design error

    - by jdk
    I'm looking for a way to fix and/or abstract away a comma-separated values (CSV) list in a database field in order to reconstruct a usable relationship such that I can properly join the two tables below and query them using LINQ and its Join method. Following is a sample showing the Person table and CsvArticleIds field having a CSV value to represent a one-to-many association with Article records. TABLE [dbo].[Person] Id Name CsvArticleIds -- ---------- -------- 1 Joe "15,22" 5 Ed "22" 10 Arnie "8,15,22" ^^^(Of course a link table should have been created; nonetheless the relationship with articles is trapped inside that list of CSV values.) TABLE [dbo].[Article] Id Title -- ---------- 8 Beginning C# 15 A Historic look at Programming in the 90s 22 Gardening in January Additional Info the fix can be at any level: C#.NET or SQL Server something easy because I will be repeating the solution for many other CSV values in other tables. Elegant is nice too. not looking for efficiency because this is part of a one-time data migration task and can take as long as it wants to run.

  • How to create a clip region from a path that includes the 'outline'?

    - by mackenir
    I am creating a rounded rectangle GraphicsPath (see red outline image below), and then using this as a clip region both when drawing graphics, and as the Region of a Form. Unfortunately, although the path looks good, it doesn't work well as a region (see solid black image below) Is there a way that I can generate a clipping region from the path that includes all the 'outline' pixels of the path? Do I need to generate a bitmap and then process this to create a region? The rounded rectangle path: When used as a clip region: The discrepancy (red pixels are in the path outline, but outside the region. blue pixels are in both):

  • GWT: stange import collision error in visualisation api

    - by parag_
    hi, I'm attempting to add two charts to a gwt page using the visualization api, but for some strange and inexplicable reason, eclipse claims that the following two imports are colliding - which makes no sense to me. In the methods where i am calling them, I have even tried using the fully qualified names, but that doesnt seem to help either. Any idea what may be going on ? import com.google.gwt.visualization.client.visualizations.Table.Options; import com.google.gwt.visualization.client.visualizations.LineChart.Options;

  • Can I configure AutoMapper to read from custom column names when mapping from IDataReader?

    - by rohancragg
    Psuedo code for mapping configuration (as below) is not possible since the lambda only lets us access Type IDataReader, wheras when actually mapping, AutoMapper will reach into each "cell" of each IDataRecord while IDataReader.Read() == true: var mappingConfig = Mapper.CreateMap<IDataReader, IEnumerable<MyDTO>>(); mappingConfig.ForMember( destination => destination.???, options => options.MapFrom(source => source.???)); Can anyone think of a way to do this using AutoMapper configuration at runtime or just some other dynamic approach that meets the requirement below. The requirement is to support any incoming IDataReader which may have column names that don't match the property names of MyDTO and there is no naming convention I can rely on. Instead we'll ask the user at runtime to cross-reference the expected column names with the actual column names found in the IDataReader via IDataReader.GetSchemaTable().
