Change Font Color Of DataGridView Header Text For Read Only Columns?

Jan 9, 2012

How to change the font color of the column header text in my datagridview if the entire column is read-only. I basically use a loop to add columns to my datagridview and then set the properties of the columns. But for some reason setting the DefaultCellStyle.ForeColor and HeaderCell.Style.ForeColor properties does not work. The header text is still black.[code]...

Reading A Blank String From Excel When Trying To Read The Header Of A Data Column?

Aug 25, 2011

I use an OLEDB connection to read from an excel database, and this loop to read in all of the data from each of the columns

While reader.Read()
For i As Integer = 0 To reader.FieldCount - 1
temp = reader(i).ToString + ControlChars.Tab
output_file.Write(temp)

[code]....

Some of the columns contain date information, which are read in fine (usually as a string "2/20/2011" or so), but the headers of those columns are read in as a blank "". The headers for all the other columns read in fine, but not for the date containing columns.

Read The "FrameSize" From The Header Of A SWF File?

Feb 12, 2012

I am trying to read the "FrameSize" from the header of a SWF file. I know it starts from the 9th byte and that it is 9 bytes long. I am getting stuck on the next part though... What I now need to do is read the first 5 bits of the FrameSize ByteArray in order to determine how many bits make up the remaining 4 sections of the tag. Then I need to read each of those sections to get the data I need.

I've been googling for ages and trying different things, but I am still clueless on howto grab the first 5 bits and turn them into a usable value that I can then use to navigate the remaining bits.

Read Text File And Stop Then How To Continue At The Last Read Point

Dec 15, 2009

I'm using vb.net 1.1 to develop the program. I got text files that contain test result from a machine, like below.

T1 1.24535 2.56335 2.43253 1.24538 2.55619 4.35243
T2 1.42542 1.63728 3.57295 4.59275 1.57320 2.72057
T3 5.12857 2.45375 6.38593 2.58375 3.57259 3.57204

I need to check the test result with the data from database, to find out which test result is failed. If there is a fail test result, I will show an alert to the operator and stop the checking process. Until the operator close the alert, then the checking process will continue from the last read point.

C# - Open A Read Only File As Non Read Only And Save/overwrite?

Sep 21, 2011

I have a number of word documents I am converting. Everything is going great until I get a file that is read only. In this case I get a Save As prompt.

Is there any way to open the file in read/write format? I should have admin privileges so access isn't an issue.

I'm using VB.net to open the files. More specifically

doc = word.Documents.Open(path, Type.Missing, False, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing)

Read Only Property Not Truly Read Only?

Jan 2, 2011

Let's say we have a class, let's call it CLS_Object for simplicity. Now, suppose CLS_Object has 2 public properties, "Name" as String and "Value" as String. These have both read/write methods into the properties.

Now let's go to a seperate class, let's say CLS_Example. Let's create this variable:

Public
_OBJ_Object as New CLS_Object

Now, let's create a property, called PROP_Object that is READ ONLY...

Public ReadOnly
Property
PROP_Object As
CLS_Object

If we allow that to return _OBJ_Object, the user can the also SET VALUES to that object. In the context of "well, the property is returning the object and you are writing to the object, not the property", I understand this behavior. But it means you can write to a read-only object of sorts.

Pass A Delegate Into A Constructor Of An Abstract Class From A Descendant's Constructor?

Feb 15, 2010

I have an abstract class which requires a delegate to function. I pass the delegate into the constructor. Now that I have a non default constructor I need to call the abstract class's constructors from the concrete class which means that I need to use MyBase.New(...). I have included a quick example below.

Public MustInherit Class BaseClass
Public Delegate Sub WorkMethod()
Private _Work As WorkMethod

[code]....

I have tried to do this but I keep getting the following error: "Implicit reference to object under construction is not valid when calling another constructor".Can I not do what I am trying to do above? I initially had the delegate setup in its own setter method. But then I am creating a deceptive API because it does require a point to a method to work properly.
