• Ronaldlee Ejalu Simple Bound Textbox Can't Retain Empty String

  I have some simple bound textboxes on a windows form. My dataset has parent and child tables. Some of the textboxes are bound to the parent data and others to the child data. When any child bound textbox loses focus after I've cleared its text it returns to its original value. For example, if I want to edit a child bound textbox value from being "test" to "" as soon as I leave the field it returns back to "test". I can add or remove part of the text without a problem such as "test1", but once I completely clear it, it returns back to original. I want to be able to clear the textbox so that I can save an empty value if need be. I have found a workaround solution at the following web site, http://w ...Show All

• Madok File creation DateTime changes?

  I have an application for updating the client files. This app reads the files from the server and compares the file creation DataTime with the files in the client machine if there is a change then it downloads the new file.

• Wilhelm Knutsen Opening a form

  VB6 is total different than this! Learning a new platform, so please excuse me for my mistakes! I have a form which needs to show one record(thats all that is needed-its a table that carries the end-users info only-so only one record). The form has got the right datasource. I maybe opening it wrong to show the data. I have got a command button on my main form to open the "Company" form, with the following code; Private Sub Button5_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click Dim MyForm As New Company MyForm.Show() End Sub The form opens, but with no data, there is data there because it is being used on the main form.

• Casper Thomsen Design question reading data

  Hi I sometimes include reports and charts in my apps. If I need fast cube like functionality I load lots of data into memory from the db. Then I use nested For Each... to read the data form the objects. Sometimes I have 4-5 levels (first object have a collections and each object in that collection have their own collections and etc....) I have never had any problems doing this, but clearly this is not best practise (first of all since the number of transactions is unknown). I have tried to find a vb.net sample code on this but no luck. Could someone point me in the right direction. Thank you. Hi imnotbillg, It's hard to say what a best practice is. The reason this is hard to say is because there are many variables to deter ...Show All

• kennm vb6->.NET 2.0 conversion 'ByVal sName As Any' argument for c++ 'char szName[128]' param

  what would be the appropriate .NET 2005 equivalent parameter be for this vb6 pinvoke declaration Public Declare Function foo Lib "foo.dll" ( ByVal sName As Any ) where the c++ argument for the parameter sName is is 'char szName[128]' Related question (I hope) I am confused as to when I should use 1. <MarshalAs(UnmanagedType.LPStr)> ByVal sVar as String rather than simply 2. ByVal sVar as String for cases where the vc++ parameter is char *sVar Thank you, -Greg No, ByValTStr is only used within structures when you want to declare a fixed size char array. If you want to send the full 128 bytes as a "char *" paramet ...Show All

• Bubo Trouble accessing module from custom user control.

  I have a seemingly strange situation. I have module in my solution called IO. I use it, among other things, to share some variables amoung classes. In it I have a sortedDictionary called variables and properties (readonly) getVariable and (writeonly) setVariable. I have been able to use these properties fine in all of my classes until I try tried doing so on a custom control. My custom control exists and is already placed on a form. I then add the IO.getVariable(varName) statement to the custom control and complile. It compiles fine, but once I go back to the form on which the custom control is already placed, I get an error saying that "object IO not set to instance of object", and the form will not show.

• felix1000 Retrieve milliseconds from MS-Access Date field

  Dear Readers, I have a Access database, which stores the time of each record in a date/time field. When I add a record to the database using the INSERT query, the time is added correctly, including the milliseconds parameter. When loading the parameter value with the time I can confirm this milliseonds component is present and correct. In my report I provide a list of records, which displays the time with it milliseconds component. The time is correct, but the problem is the milliconds is always 0. It looks like the database cannot store the time in hours, seconds and minutes, but not milliseconds. Is it possible to store the milliseconds component in a date/time field of a Access database . Thanks Ma ...Show All

• sl0140 running a function (w/ return) in a seperate thread?

  hi all, i have a piece of code that tests a db connection and returns a boolean value. this may take a while, so i have made a form with a marquee-style progress bar to display while testing. problem is, the form shows, but the controls (progress bar) don't. i can't run the testing function in a seperate thread ('cause it has the wrong signature - i hear this is completetely impossible ) and when i try to run the form.show in a thread, this doesn't change anything. i also tried to run this whole thing below ( except the form showing part) in a different thread but then i get exceptions because the other thread can't access the controls. i'm pretty new to this whole thing so it's probably me being stupid, but anyway. my code (i ha ...Show All

• Charles Tam populating an Access database using visual basic 2005

  I am trying to create a new employee application that gets input from a user in text boxes and then take that information and populate a database in Access that will later be pulled to the Track IT! database on SQLserver2005. How do i do it Thank you. THANK YOU!!!!!! Good Answer! correct. Basically if you have 5 fields in a table, then you need 5 parameters but it depends - if some of the fields are left to be nullable, in other words data in that field is not required, then you only need as many parameters as you like. so if i had 5 fields and all of them were set to be do not allow nulls (or whatever the MS Access equivelent is of this) then I would h ...Show All

• ble0t set up and query database with 2 text and 1 image value

  Hello Everyone, I need to write a code where i can save three things: all the files in a folder with full path (fullpath), the name of the files without extension and full path (FileName), and the icon (icon) of it into a database, and after this all, i need to query the database according to the FileName. When typing i'd like to add all the database items that includes the string i am searching for showing their icons also. On starting the app, I need to load the database from a file and when exiting it, i need to save the database into the same file overwriting it. I need this because if i want to search a folder with a lots of files it takes too long to find something but i think from a database it'd be more faster. If anyon ...Show All
