VS 2008 Adding Additional Components?
Dec 13, 2009
I need to make a custom control and decided, before that, to see if there were any additional components that I could utilize.When looking through the list, I found a component called an Expander. So I decided to add it and see how it works.
After adding it, I couldn't find it at all within the toolbox. I went back to Choose Items and it was checked, but still not in the toolbox.It's probably important to note that it is a WPF component and this is not a WPF Project. Would that make a difference?Is there something else I may be doing wrong?

I'm am very new to Vb.net, I have coded in VBA.I have created a form that will open Microsoft Excel, add header text to the columns, and insert the text from a few of the controls located on my form ("not finished adding controls") when I click the Submit button.
My problem is that when I enter different data into those controls and click the submit button again, I get a new Excel Workbook with the new data.I need the new data the be submitted to the .Activecell.Offset(1,0) of the already open workbook.Ultimate Goal of Submit button is to open new Excel workbook, Enter multiple rows of data via Visual Basic Form.

I have a line of data that represent a data import. When the import is done, I would like to keep that exsisiting line, and add another line for the next import. So I have a display of mulitiple lines, showing multiple Imports.So this is one I have for the first section, it loops through the data so you see the rows incrementing
TextBox1.Text = clsDatRow.iFirstVal.ToString + " ROWS:" + iCountRows.ToString + " " + Date.Now.ToString
TextBox1.Refresh()
Now, I can I keep the line of data, and add a new line so for the next import, it does the same thing. It ried vbnewline, but it just clears that line, it doesn't move down to a next line.

I'm copying code from one VB project to another PC but the 'datagrid' on the copy insn't inserting into the new PC. When the form loads the datagrid is missing. The error I got was that there was something missing from the machine. When I tried to add the datagrid using the 'Additional Controls' it doesn't seem to exist. Any chance I can download the control? The version of VB is 6.5 and its part of a graphics package I'm using.

I'm loading my listview with records from a mySQL Table, which works great. But I'm having issues when I try to add records to another listview according the selected row in the first listview.
vb.net
Dim mysqlDataComm As New MySqlCommand("SELECT jan, feb, mrt, apr, mei, jun, jul, aug, sep, okt, nov, dec FROM data_table WHERE datum ='" & frm_main.Listview1.SelectedItems(0).SubItems(1).Text & "'", mysqlConn)Dim mysqlReader As MySqlDataReaderTrymysqlConn.Open() With frm_main.lstv_data.Items.Clear() mysqlReader = mysqlDataComm.ExecuteReader While mysqlReader.ReadDim lvi2 As New
[code]....
It works until ".Items.Clear()"... after that nothing happens and I really don't know what I'm doing wrong. No error, whatever.

Can a BackgroundWorker call additional subs? In my program I am connectiong to an OPC Server. I am doing some AsynReads, which in themselves don't take anytime. But Once I get the AsyncReadComplete returned, I want to do the AsyncRead right away. Basically I need to Loop them. The problem now is that while it is doing this, Everything is unresponsive, because it is just going through the loop. So to perhaps rephrase the question, If the BackgroundWorker initiates a process (in this case AsyncRed) would the returned AsyncReadComplete be apart of the BackgroundWorker or seperate Thread?

I would like all additional forms opened by some command the user performs on the Form1 to open in the center of Form1, no matter where the user has physically moved Form1 on their desktop screen. The application itself (Form1) is a small box with dimensions of 442x306 that will open even smaller forms on top of itself. Right now, I have everything positioned to open in the center of the screen so, in theory, everything works/looks fine as long as the user doesn't move Form1 anywhere.

I have an ExtendedDateTimePicker control on my form. When I attempt to change the "ShowCheckBox" property to true, VS2008 stops responding and eventually exits the application; losing any unsaved changes.
I then tried to changed the property in code and the same result.
I want the control's value to be blank when it initializes.

OK maybe this is completely silly question that everyone knows the answer to but me! Is it possible to hide a component while in design view? e.g. I'm working with multiple components that overlap and would just like to be able to view/work on one at a time. Have I completely missed something or is this not possible?

We have currently upgraded our development machines to Windows 7 and Office 2007. We have a vb 2008 app that references 2003 Office components to use for mail-merging to word.We loaded up our app in the vb environment today and were instantly greeted with missing components/functions which are related to the 2003 Office components. We can update these to use the Office 2007 components/functions instead, however we are unsure whether after doing this our vb app will work with machines only with Office 2003 on. can machines with Office 2003 on work with our vb app that references Office 2007 components?

I think (?) this is about object design, and perhaps about structural and/or creational patterns. But a bit hard to say when I only know a couple of patterns yet.[code]But... what if we INSTEAD want each Product instance only to (in some way) refer to one instance of a specific list of Components. So we wan't to save the products list to one file, and the components list to another file. Then would I build the objects the same way, or different? So let's then say we have now Class B as below. [code]
1. Will not need to update each component variable of the products list when the components list changes.
2. If the Product object shall be shown in a DataGridView, for editing properties, it seems easier to implement the selection of the component property.
Is this wrong approach? Is it suitable in some cases, and if so, when? Are there other solutions I perhaps am not aware of that would be appropriate? Is this about structural design patterns? and if so, can the alternatives above be catagorized to some pattern type? I don't really know exactly what I'm looking for.. But I think probably I'm looking to understand whether the object design will be determined by the way the objects are saved.. And if i shall save the objects by serializing to file, vs saving to a database, would I create the business objects differently?

I have a parent/child relation I am trying to create fow 2 datasets.The parent ds consusts of a range of PO Header information
After I fill this dataset I loop through it getting the PO number. I then take that value and execute another sql statement on the DETAIL file and fill a dataset(dtlDS) for EACH row in the parent. How do I add to this dtlDS for each row? I am getting no CHILD data in the merge. Should I be filling to a datatable and do an add.row and THEN dump into the dtlDS?

adding certain functionality to an existing ASP.NET application running on IIS 6.0 programmed in VB.NET.To aid in future development the client wants the additional functionality to be as future proof as possible. Ideally i have said that I would like to push for a solution using ASP.NET MVC3, running off IIs 7.5 and .NET 4, written in C#. This solution would act as a seemless addition to the current web-portal appearing probably just as an extra tabbed page.
But they will be completely seperate web-apps. Which is crucial.The main problems i can forsee are firstly sharing session particulars between the asp.net web app and the new application. Particularly with regard to maintaining session state (and not having IIS timing out on one of the apps). Also, conjoining the two "apps" appears problematic in my head, although this may be far simpler than i fear.
1) Embed the new fuctionality into the existing codebase (not a great option). This would mean losing any potential future upgrade-ability and also means not following better OO conventions by utilising the MVC framework.
2) Using an iFrame to link to the razor pages of a seperate MVC3 app (the one im favouring currently). Allows uses of all new technologies, however downside is sharing session data. Either through iFrame "attributes" through persisting a session state to a db? (slow?) or even some kind of web service interaction between the applications to push/pull user/session data?

Im practicing a database and I have a 3-column table. Im using binary formatting to save/open the file. I cant see what is wrong with my code“
I can display records ok when I press the save button
I can also save the records ok when the save/close button is pressed.
When I reopen the programme and press the reload button to reload the dataset, additional records will not be displayed nor saved though original records will be showing.[code]...

We have a big Form class that we like to split into peaces using partial class approach That could be done by manually modifying a project file, and adding MainFormPN.vb entry
<Compile Include="MainForm.vb">
<SubType>Form</SubType>
</Compile>
<Compile Include="MainForm.Designer.vb">
[code]....
The issue with this approach is when double click on this item in VS2008 IDE it shows new empty form, not MainForm UI. It looks like VS2008 does not support multiple partial classes for a Forms.

I am using a webbrowser control and loading a website that uses basic authentication. I pass the username and password in the additional header of the navigate routine. The problem is that the header is not retained while navigating the site.
I.E.I log into the site and pass the user name and password in the http header. When I click a link to access another page the header is removed and the site asks for credentials. If I was to just type the site into IE and log in the first time the headers are carried forward on all pages. how I can have the page retain the headers so the user never has to authenticate?
Dim sHeaders As String
Dim HelpBrowser As New WebBrowser
sHeaders = "Authorization: Basic: " & System.Convert.ToBase64String(System.Text.Encoding.ASCII.GetBytes("UserName:Password")) & Chr(13) & Chr(10)
Me.HelpBrowser.Navigate("http://www.mysite.com", True, Nothing, sHeaders)

I need to add an additional dimesion to outputArrayOfBits() in the code below which I hope conveys my intention. I need to convert a one dimensional array of 1 to n boolean (bit) values into arrays that group them by 8's so the output can be consumed by someone needing these values to be in hex format (0000 1111) = 0F How do I change the declaration of 'outputArrayOfBits and the nested control loop to achieve that?
Dim inputArrayOfBits As New BitArray(32, True) ' I can't change this.
'Create array of bytes containing what will be sent out has hex numbers 0 - F
'outputArrayOfBits(0) = (1,1,1,1,1,1,1,1) 'Hex value FF

I want to show tblProductComponents and have only the PercentValue the only value that can be updated. But, I also want to show the component information as well.I can do this in a view but then I lose the update ability using the tableadapter.
