You use OLE Object fields to insert documents (Word, PDF, bitmap images, etc) into records. The OLE Object itself is actually a binary data field and the only way to compare any two OLE Objects is to compare the binary data itself. This makes no sense because we normally compare documents by type, size, author, title, creation date, last modified date, and so on, we don't compare their physical representations (the binary data itself). If we want to sort documents, we must extract the properties we wish to sort by and insert them as separate fields in our records, and use those fields as our index/sort keys.
Sometimes we really do need to use binary data as a sort key, but we cannot use an OLE Object to store that data because OLE Objects cannot be used as sort keys. Instead, we must use the built-in binary data field which can be indexed and sorted. Binary data fields can be fixed-length (binary) or variable length (varbinary). Note that OLE Objects are variable length with a theoretical limit of 1 GB, which is yet another reason why they are unsuitable for indexing. The fixed-length binary field has an upper limit of 510 bytes, making it ideal for indexing and sorting small amounts of binary data.
Unfortunately, the built-in binary data fields cannot be created using the table designer for no practical reason other than Microsoft decreed that you couldn't. Instead you must use DDL or VBA/DAO. Using DDL, the following will create a binary and a varbinary field. For completeness, I've also included an OLE Object field:
CREATE TABLE tblBinTestSQL (
Id counter NOT NULL PRIMARY KEY,
VarbinaryColumn varbinary(100) NULL,
BinaryColumn binary(100) NULL,
OLEColumn Longbinary NULL
);
Here's the VBA/DAO method of achieving the same thing:
Public Sub CreateBinaryColumns()
Dim td As DAO.TableDef
Dim db As DAO.Database
Dim fd As Field
Set db = CurrentDb
Set td = db.CreateTableDef("tblBinTestDAO")
Set fd = td.CreateField("ID", DataTypeEnum.dbLong)
fd.Attributes = fd.Attributes Or dbAutoIncrField
td.Fields.Append fd
Set fd = td.CreateField("BinaryColumn", DataTypeEnum.dbBinary, 100)
fd.Attributes = fd.Attributes Or dbFixedField
td.Fields.Append fd
Set fd = td.CreateField("VarbinaryColumn", DataTypeEnum.dbBinary, 100)
td.Fields.Append fd
Set fd = td.CreateField("OLEColumn", DataTypeEnum.dbLongBinary)
td.Fields.Append fd
db.TableDefs.Append td
End Sub
Once you have at least one table with a binary or varbinary field, you can simply copy that field to other tables. You can also modify the properties of those fields in table designer; you just can't use table designer to create those fields.
Either YOU get an error message, or YOU access some random memory address causing unpredictable effects.
The z-index in CSS controls the levels of all of the elements. for instance if you have 2 absolutely positioned DIV's that are overlapping you could set the z-index on one to 5 and the other to 10 and the one with the higher z-index will appear on top.
Only one button needs to be created in the first place, with its caption set as whichever number between 0-9 that you want. After it has been set to the appropriate size, the button needs to be copied, so that the index property will appear. It would help to set the index to the same number as the caption, to avoid confusion. The code, as it turns out, is relatively simple: Private Sub Form_Load() Dim index As Integer End Sub Private sub cmdKeyPad_Click(index As Integer) txtKeycode.Text = txtKeycode.Text & cmdKeypad(index) End Sub
Use the array suffix operator [] to access the individual elements of an array through a zero-based index.
If you mean that you try to access an index outside of the bounds of the array, then it will result in an IndexOutOfBoundsException being thrown.
For an array of length s, the last element has index s-1.
Access automatically creates an index for the primary key field in a table. In addition, Access automatically creates an index for any field name that contains the following letter sequences: code, ID, key, or num.
An index is a systematic way of referencing an ordered a set of objects.
