• Robert F Bouillon textbox visible priority set to "false" will not keep value (how-to use Form Field)

  Hi, This should be simple to do but I just can't figure how to fix the problem. I have a form with one master table and 20 other tables showing related data. The data is linked by the key value in the master form. For example, I have a "Long_Desc" variable in the master table which holds the ky value for the descriptions I keep in the "descriptions" table. Maybe I am doing this wrong but I in my test, I was displaying the content of the key "Long_Desc" in a read-only TextBox just to make sure I was getting the right record from the "descriptions" table. I could also display the content of the "Long_Desc" TextBox using a messagebox. Now, I would like to hide the the "Long_Desc" field on the form. I set the "ReadOnly" priority to True and "T ...Show All

• Pedro Felix Two Bugs in HTML Select Element

  I believe I have found 2 bugs in the Select HTML element. If you enter server-side of: ddService.Items.Item(index).selected = true ddService being the ID of the <select> element with a runat="server" attribute the code that is generated is <option selected="selected" value="3233">Some option text the proper structure is <option selected value="3233">Some Option text The same is true for the multiple attribute. the code that is generated is multiple="multiple" Microsoft's own documentation states that the proper values for selected and multiple are true/false.

• Joe H. BITBLT not working?

  I have 2 bitmaps in memory; one is an original copy of a picture and the second I intend to block out parts of, and display it. my bitmaps are named b1 and b2. b1 is loaded from a file (and converted to a 32bpp bitmap along the way) b2 is created with the same height, width, pixelformat, horizontal and vertical resolutions. (but empty) I then attempt to copy part of b1 into b2 using BITBLT. (I don't want to use Graphics.DrawImageUnscaled - the reason being that I intend to copy parts of the image in the future) I assign b2 to a picturebox, but it displays a blank image. Here is the code which doesn't seem to work: pbox2.Image = Nothing Dim g1 As Graphics = Graphics.FromImage(b1) Dim hdc1 As IntPtr = ...Show All

• MatthewMaas Listbox

  hello, How can I retrieve the values the user selected from a listbox with a selection mode set to = SelectionMode.MultiExtended From what you appear to have done - you need to specifically cast each item to a datarowview which is probably what was used in the databinding scenario. The following code show demonstate this - most of the form load is creating a datatable and then a dataview from it which is being used for the databinding on the listbox. The button click event will display the selected item values.

• NeoNmaN Special Characters in XML File

  Hi all, I have a little problem with XML. This XML file is a UTF-8 codeification and most of the times a "tiny square" appears inside the text, I know I can replace the character but I just don't know which character is. Working with VB.NET (System.xml and System.XML.Path), I tried to get the char number but I get two values: 63 and 13 Dim CharWeird As Char = GetChar(xString, 15) ' 15 is the position of the character (zero based) CharWeird = 63 BUT if I.....

• furjaw unable to cast COM object error

  Hello, I am having a strange problem that I can't seem to figure out. I am using visual studio 2005, visual basic, .net 2.0. In my application I am using the Microsoft Internet Controls COM object to automate an Internet Explorer instance. The whole application runs fine in debug and release on my development WindowsXP machine. When I publish the project to Windows Server 2003 to run as a release, I receive the following error. I was reading some posts on registering COM components, etc, but I was not sure why this would run fine on my dev machine and blow up on the release box. Both machines have the same versions of .Net on them. Any insight on where to go, or how to register the COM component would be appreciated, as I am new to ...Show All

• Bigmo wrong Count of Records

  Hi, I am having troubles with the count of records in a Form. All my Tables used in my Access database are linked tables to an SqlServer. The Form I use is a wizzard created form and the recordsource is simple like "SELECT * FROM tab1 join tab2 ..". I want to display the number of records in the form, but it seems, that the recordset does not load all records at once. What i did is: Private Sub Form_Current() lblRecordCount.Caption = Recordset.RecordCount End Sub But when I open the form, it displays just "16", if i move to a record below, it changes to "28", when i scroll to the end it finally displays "100" - which is really the right count. I tried this also with a new database, where i created a table with 500 records ...Show All

• wencey combining datatable and buttonGridCell in dataGridView

  I have a dataGridView that I would like to consist of a couple regular columns, then an buttonCellColumn, then a imageCellColumn, followed once again by a regular column; text text buttons images text; I would like each of the text columns to be bound to a datatable, but don't necessarily need the buttons and images to be (though its fine if they are). Q1. Considering I have 18 rows, is this OK to do from a GUI performance point of view (the images will be very small) Q2. In general terms, how do I do this. I know how to create the datatable, bind the dataGridView. I can even add the buttonImageColums. The part that confuses me is then adding the final text column - since I really want it to be part of the bound data ta ...Show All

• Andrew Buyan Use a class passed by reference when the unmanaged function demands two levels of indirection.

• S. Visual Basic 6.0 and MS Access linking pictures!

  Hey all, im a student in a UK college, using VB for my coursework in computing. Basically, i can't get a hold of the code for something which i think is important in my project. First, let me put it into context, my project consists of a program for use in an opticians, so "stock control" is one of the forms. Thus, i have a database of the available spectacles, linked to the form via an ADO control. My intention was to place images in the database, then have a set space on the form in which the image will change according to the record. E.g. if i move "next, next, last" the image would correspond to the last set of spectacles. I tried a basic hyperlink from the directory in the database (which is MS access btw) but that didn't seem t ...Show All
