Everything worked great this morning on my ASP project. Suddenly, I have 48 errors. Similar to the following:
Name 'pnlVars' is not declared
'txtPolicyNo' is not a member of 'LetterWriterASP.UW'
Seems every control I reference is now no longer declared or not a member of my project. I checked the page, the controls are all there with the same names & IDs.
In VB2008. Project has been running fine for months. But today many of the controls on my form, say they are not recognised and it's saying they are not declared. They are form controls, textboxes, comboboxes and labels, they are spelt correctly. If I double click a combo box, it takes me to the SelectedIndexChanged event for that control. Yet the combo box is not recognised in that procedure. E.g. MyCombo.Text, has an error of MyCombo is not declared.
This happened after changing the font ForColor for lots of controls at the end of last week. At least that was the last change I did before closing my project at the end of last week. The form has a tab control on it and this is only a problem for the controls which I changed the forcolor for. Tabs which I did not do this do, continue to work perfectly. The control names are not in IntelliSense.
I am desinging a form with mutiple controls on a tab page control and was moving controls between tab pages by cutting and pasting them. The forms designer obviously got confused at some stage and I now have controls that are declared in the designer.vb but do not appear anywhere on the form.
I can't even rename the controls that are there which have been given generic names to the names I want because they apparently already exist. I realise I could edit the designer.vb and remove the references to these controls but that seems fraught with danger?
The following is a screenshot of the problem: What can I do?

I haven't touched a project in about 8 months. It's ongoing for work, but hasn't really been published fully so it gets worked on in my spare time. I went to recompile and the build failed. It had previously worked. I can't figure out why. Part seems to be due to AxOWC11 being recognized, but it shows up in the namespaces. I'm looking for the .dll that shows up as AxOWC11.dll, but I'm not seeing any. I do have one that shows up as AxInterop.OWC11.dll and I do have just a OWC11.dll in my list. I've posted some of the errors below.

I have an application with several forms. The form Main.vb has always been editable in the designer. However, this has changed. The icon in front of the name has changed to a module icon, and the designer and code are no longer found. When I run the application, it still functions as expected.
View 4 RepliesI am trying to add records from an Access Database into another Access Database using DAO recordset.The VB.NET program would add the records until it hits random stop and error says "Object invalid or no longer set". what would cause this? The recordset contains 7 million records, but it only added approx 6000. Next time i run the program, it would add different number of records again.

I have run into a small little annoyance while writing a program. I have a bunch of controls on the form and while trying to figure something else out they all got parented to another control, using undo I unparented them from that control however now when the control is clicked the code that is in the sub for them does not run at all. If I double click the control it generated an entirely new sub with a number i.e. what was "Private Sub NumericUpDown1_Value Changed" becomes "Private Sub NumericUpDown1_ValueChanged_1".Near as I can figure the subs with the code are no longer associated with the controls.Is there a quick way of fixing this or am I stuck copy and pasting the code from each sub into a newly generated one?
View 3 RepliesI know .NET no longer supports DDE however unfortunately most "Finance" related programs (ie, charting and data vendors) use DDE to tie into their data. (Ie, esignal, Marktfeed etc). I've been toying around with NDDE however I'm having a hard time implementing it...unless I'm just making 1 request then it's fine. My question is would it be possible to take VB6 Label Control since it has the "Linkmode, LinkTopic, LinkItem, Label_Change" Properties/Methods and events in it....and create something like DDELabel.dll via Activex control project then use that as part of VB.net?
I tried doing it via the Control Wizard then using it in .NET however I know for a fact I'm not doing it right. Perhaps if someone much more competent could attempt it see if it does give the DDE functionality when used in .NET they can point me in the right direction...
After reading through several forums, which suggested that I should add a referenced DLL (whose source cod I have) to solution as an added project, I am unable to step through the code of the referenced DLL that generates an error. I also turned off"Enable just my code" from Tools->Options-> Debugging. However, I am still not able to step into the referenced DLL's code I added the pdb file and the referenced dll to the bin/Debug folder of the original code that I am working on

When I place a breakpoint on that line and add a watch it says the value is "Referenced object has a value of 'Nothing'"How can I check for a value of nothing? I thought that is what the IsNothing was for. I have tried Convert.ToString() and still the same result.

My.Application.MinimumSplashScreenDisplayTime = 10000
Which I reckon should keep the splashcreen open for 10 secs but it doesn't - infact nothing does. So my question is how do you keep the splashcreen open for longer? The above code is in the splashcreen form loading events and I think that that is the issue but where elses can I put it?
I used the thing where u go to properties and select a splash screen but how do i make it longer?

I'm generating a list of names from my database, but I need to validate them so they are no longer than 15 characters.
Dim Name As String
Dim txtFirst = "../../Names/first.txt"
Dim txtLast = "../../Names/last.txt"
[Code]....
I need Name to be no longer than 15 characters, and it doesnt matter if the name stays in tact, it just needs to cut off characters from the end of the string until its 15 or less.
I would like to be able to fire/trigger an event when the form is no longer the top most window (ie the window that is on top of all other windows), and then close the form with me.close()

View 1 RepliesI have an API that loads into memory from a button click. It can then either load an approx 10MB txt file (ASCII comma delimited characters/decimal list as a string) or live timed data from the internet. The idea is to be able to view the data in a text box. From there I can see what I am doing as far as spitting that info into a datagridview or database. The data is completely out of order in the txt file but has various Getinfo Functions / DLL's accessed via button clicks that split the data into its correct format to display in the text box. The problem I am having is not having fixed length strings in VB 2010. I don't know enough to work out if there is a simple work around or something more complicated required. Everything I have tried has left the textbox empty.
