  • Generic TypeIdenitifier convertion.How?

    - by John
    How do I convert the TypeIdenitifier to a class type? I need to use implicit convertion. type TMyChildArray<T>=class(TMyArray<T>) private FData:Array of T; procedure AddEnd(); end; TTypeIdenitifierParentClass=class(TAnotherParentClass) protected TestField:Cardinal; end; procedure TMyChildArray<T>.AddEnd(); var elem:T; begin for elem in Fdata do TTypeIdenitifierParentClass(elem).TestField:=0; end; I get "Invalid typecast" on the implicit convertion "TTypeIdenitifierParentClass(elem).TestField:=0;". The principle I want to use is that the TypeIdenitifier will represent a class that descends from TTypeIdenitifierParentClass.There are many class types,but all of them descend that class. How do I do this?

    here is a hybrid cable for QSFP to CX4. Will this fit SFP+ ports? Deeply confused by standards and struck in a situation with wrong hardware selection!Personally have not seen the ports/hardware and hence the obviously stupid question! thanks for stopping by and bearing with me. http://www.cablesondemand.com/pcategory/72/category/QSFP+-+CX4/URvars/Catalog/Library/InfoManage/QSFP_TO_CX4_COPPER_CABLES.htm

  • utf-8 convertion doesn't work always

    - by Marco Piccinni
    I searched into other stack before to type here and I didn't find anythong similar. I have to scrape different utf-8 webpages which contain text like "Oggi è una bellissima giornata" the problem is on the characther "è" I extract this text with jtidy and xpath query expression and I convert it with byte[] content = filteredEncodedString.getBytes("utf-8"); String result = new String(content,"utf-8"); where filteredEncodedString contains the text "Oggi è una bellissima giornata". This procedures works on the most webpages analyzed so far but in some case it doesn't extract a utf-8 string. Page encoding is always the same as the text is similar. Any ideas about the problem? thanks Marco

  • Generic Dictionary - Getting Convertion Error

    - by pm_2
    The following code is giving me an error: // GetDirectoryList() returns Dictionary<string, DirectoryInfo> Dictionary<string, DirectoryInfo> myDirectoryList = GetDirectoryList(); // The following line gives a compile error foreach (Dictionary<string, DirectoryInfo> eachItem in myDirectoryList) The error it gives is as follows: Cannot convert type 'System.Collections.Generic.KeyValuePair<string,System.IO.DirectoryInfo>' to 'System.Collections.Generic.Dictionary<string,System.IO.DirectoryInfo>’ My question is: why is it trying to perform this conversion? Can I not use a foreach loop on this type of object?

  • character to the corresponding virtual-key code in c#

    - by kambamsu
    Hi, Currently, i'm using the method "VkKeyScan" in the win32 api to convert a character to its virtual keycode. But the problem that this seems to have is that, when i pass small alphabets, it works fine whereas when i pass in a capital alphabet, it doesnt return the appropriate keycode and similarly with special characters like "(" or "}" .. How do i do this? Is there anyway for me to directly convert a string to its virtual equivalent without considering whether it contains capitalized or special characters? Thanks

  • Map tiling - What kind of projection?

    - by ikky
    Hi. I've taken a large image and divided it in to square tiles (256x256). It is made for google maps also, so the whole image is divided into z_x_y.png (Depending on zoom level). z=0 = 1x1 tile z=1 = 2x2 tilesthe z=2 = 4x4 tiles My imageMap is "flat" and is not based on a sphere like the worldmap. I'm gonna use this map on a windows mobile app (which has no google API), and all the "points of interests" is inserted into a database by longitude and latitude. And since i have to make this for the windows mobile, i just have XY coordinate system. Is it enough to just use this: MAP_WIDTH = 256*TILES_W; MAP_HEIGHT = 256*TILES_H; function convert(int lat, int lon) { int y = (int)((-1 * lat) + 90) * (MAP_HEIGHT / 180); int x = (int)(lon + 180) * (MAP_WIDTH / 360); ImagePoint p = new ImagePoint(x,y); // An object which holds the coordinates return p; } Or do i need a projection technique? Thanks in advance. Please ask, if something is unclear.

  • Does informing your destination hardware impact on ebook convertion on Calibre?

    - by Roberto
    If I connect my Kindle Fire to the computer, Calibre gives me an option to convert to Kindle Fire mobi format. Is this different from just asking to convert to mobi? I don't want to connect my Kindle anymore, I want to send to the cloud, but I'm not willing to lose conversion quality because of lack of ebook reader information. Of course, I couldn't find the convert to Kindle option without it being connected.

  • Using CTAS & Exchange Partition Replace IAS for Copying Partition on Exadata

    - by Bandari Huang
    Usage Scenario: Copy data&index from one partition to another partition in a partitioned table. Solution: Create a partition definition Copy data from one partition to another partiton by 'Insert as select (IAS)' Create a nonpartitioned table by 'Create table as select (CTAS)' Convert a nonpartitioned table into a partition of partitoned table by exchangng their data segments. Rebuild unusable index Exchange Partition Convertion Mutual convertion between a partition (or subpartition) and a nonpartitioned table Mutual convertion between a hash-partitioned table and a partition of a composite *-hash partitioned table Mutual convertiton a [range | list]-partitioned table into a partition of a composite *-[range | list] partitioned table. Exchange Partition Usage Scenario High-speed data loading of new, incremental data into an existing partitioned table in DW environment Exchanging old data partitions out of a partitioned table, the data is purged from the partitioned table without actually being deleted and can be archived separately Exchange Partition Syntax ALTER TABLE schema.table EXCHANGE [PARTITION|SUBPARTITION] [partition|subprtition] WITH TABLE schema.table [INCLUDE|EXCLUDING] INDEX [WITH|WITHOUT] VALIDATION UPDATE [INDEXES|GLOBAL INDEXES] INCLUDING | EXCLUDING INDEXES Specify INCLUDING INDEXES if you want local index partitions or subpartitions to be exchanged with the corresponding table index (for a nonpartitioned table) or local indexes (for a hash-partitioned table). Specify EXCLUDING INDEXES if you want all index partitions or subpartitions corresponding to the partition and all the regular indexes and index partitions on the exchanged table to be marked UNUSABLE. If you omit this clause, then the default is EXCLUDING INDEXES. WITH | WITHOUT VALIDATION Specify WITH VALIDATION if you want Oracle Database to return an error if any rows in the exchanged table do not map into partitions or subpartitions being exchanged. Specify WITHOUT VALIDATION if you do not want Oracle Database to check the proper mapping of rows in the exchanged table. If you omit this clause, then the default is WITH VALIDATION.  UPADATE INDEX|GLOBAL INDEX Unless you specify UPDATE INDEXES, the database marks UNUSABLE the global indexes or all global index partitions on the table whose partition is being exchanged. Global indexes or global index partitions on the table being exchanged remain invalidated. (You cannot use UPDATE INDEXES for index-organized tables. Use UPDATE GLOBAL INDEXES instead.) Exchanging Partitions&Subpartitions Notes Both tables involved in the exchange must have the same primary key, and no validated foreign keys can be referencing either of the tables unless the referenced table is empty.  When exchanging partitioned index-organized tables: – The source and target table or partition must have their primary key set on the same columns, in the same order. – If key compression is enabled, then it must be enabled for both the source and the target, and with the same prefix length. – Both the source and target must be index organized. – Both the source and target must have overflow segments, or neither can have overflow segments. Also, both the source and target must have mapping tables, or neither can have a mapping table. – Both the source and target must have identical storage attributes for any LOB columns.

  • Oracle: set timezone for column

    - by dbf
    Hi, I need to do migration date-timestamp with timezone similar to described here: http://stackoverflow.com/questions/1664627/migrating-oracle-date-columns-to-timestamp-with-timezone. But I need to make additional convertion (needed to work correctly with legacy apps): for all dates we need to change timezone to UTC and set time to 12:00 PM. So now dates are stored in local database (New York) timezone. I need to convert them this way 25/12/2009 09:12 AM (local timezone) in date column = 25/12/2009 12:00 PM UTC timestamp with local timezone column. Could you advice, how to set timezone for date value in Oracle (I found only suggestions how to convert from one timezone to another) (for example in Java there is setTimeZone method for Calendar objects). We want to make a convertion this way: rename old date column to NAME_BAK create new column timestamp with local timezone iterate over old column for not-null values set timezone to UTC, time to 12:00 PM drop old column after testing of this migration
