Load Event Skipping Lines?
Nov 4, 2009
The load event goes through two different List(of T) in its own For Each loop. When the form is run for the first time, the first list is populated, the second one is not so the first loop runs but the second one does not. Then an integer that would normally be modified by the second loop remains at 2 and is assigned to a private variable integer, _handsRemaining.
Here is what it DOES. It runs through the first For Each loop and populates the appropriate field. It ignores the second loop because there are no weapon Class instances in that list. Then it goes wrong. It IGNORES the remaining lines (including the third MessageBox.Show) and somehow assigns a value of 0 to the private variable, _handsRemaining.
Private _handsRemaining As Integer
Private Sub Inventory_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim hand As Integer = 2

I have a text file 'source'. I want to skip 4 lines then grab the 17th through 33rd characters and assign them to a variable. Then drop down to the 9th line and grab the 10th through the 19th character and assign them to a variable. Then skip to the 27th line and write each line to another file with these two variables appended to the end of each line. I can write the lines to another file easy enough but I'm not sure about skipping around from line to line or grabbing the variables.

I'm trying to execute different code depending on the button clicked (button 4 or 5) on Form1, but when I click on button5 to activitae the code on the Form2's Load event everything is Ok, but when I click the back button to return to Form 1 and click on the Button4 to activate the code on the Form2's Load event again, it doesn't active the Form's Load event, is there a way to form the form load event every time I access it from Form1?

I'm using this code to load a text file into list box.
r = New IO.StreamReader(str)
While (r.Peek() > -1)
ListBox1.Items.Add(r.ReadLine)
End While
r.Close()
But it loads the whole file into list box. I only want to load those lines of text that contain following number: 2008. It doesn't matter if the "2008" is at the beginning, middle or the end of a line.

Following on from my post yesterday (how to anchor buttons/controls to various sides of the current form when the form is resized) I have run into another problem. I am setting the width of my datagrid to be 80% of the form width on a 'form resize' event with 10% of the width at either side so it remains centred in whatever size window is available. This works fine. (mydatagrid.width = me.width/5*4)
I then decided to dynamically set the width of the 2 columns in the datagrid each to 50% of the width of the datagrid. Again, this sub is called in the 'form resize' event. This fails because the datagrid hasn't loaded the data from my sql database when the first 'resize' event is triggered. I did a bit of testing (by placing a simple msgbox statement into the resize event and the load event) and it seems the 'resize' event is triggered three times before the form's load event.
how do I stop the resize event triggering when the form loads (or at least make the load event trigger first).

I followed the last post about dgvs and have been trying to get my dgvs to have alternate colored lines on form load. In both apps I am working on I am using dgvs to display certain things. I do not like the look of a blank dgv on a form. When I tried to add blank colored lines to my dgv, it did work, but when I loaded the dgv with a dataset, it pushed my columns to the right and I had to add scroll bars to see my data.

the program compiles properly, however during the saving and loading part of the code, "btnSave" and "btnLoad" subs, the program only saves the data from one of the text boxes even though it should loop 4 times.

This is my frist post on the forum So I hope I am giving enough info, If not let me know if there isanything I missed.I have currently completed a project where I do a Query in SQL Server 2000 in VB 2010 and produce reports for each Tax id. When I Debug the program it finds the number and processes the reports, when I just let it run as an executable it does not pick up or find the number.
This number happens to be the last number coming back from the query and it processess in a loop while Not filename.EOF it goes thru 4 seperate routines and then loops back to get the next taxid. I did not put any routines to sleep and I am thinking maybe the application is just stepping on itself, could this be right? Thecreatereport path does a sql execute for the appropriated Table against the TaxID an the current Cycledate, then produces the report va CR2010(beta) and exports it as a pdf file to a directory on the shared sever.

With the code above, I'm trying to create and insert records into a MySQL database. The issue here is that not all records are inserted. If the XML document I'm reading from has 80 records, only 40, or 66, or some other number get put into the database. I'm guessing this is because the code is trying to insert the records faster than the database can handle them? What would the correct way to make sure the record is in the database before moving on to the next one?

My Application uses For...Next loops to read a spreadsheet into a DataSet and then display information from it based on the results of search conditions (search term and a date range).I'm having a problem with the data where, if I run a search that should return the first 400 rows in the spreadsheet, I'm only getting around 200 results. I know the search should return the 400 rows because I checked it in the spreadsheet before running the search.I think my problem might be caused by my date comparisons. I think the problem might be that I'm comparing String valueHere's my code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If ListBox1.Items.Count <> 0 Then : ListBox1.Items.Clear() : End If

I have two datatable that I pull information from a db. I have a complicated form, and I have found it easier to write a simple SQL statement to pull the records. I have then used other controls on the form to trim the info down even further. When a particular falls out of the secondary control it is then deleted from the datatable.
I am then going back through the datatable and performing other actions on the datatable. When I narrow the information, sometimes I'm getting a DeletedRow is inaccessible. I have been looking at a way to do an IF statement to see if a row has been deleted, but I haven't figured out a way to skip a deleted row. Is there a way to skip a deleted row that I'm not seeing.

I'm hoping somebody can help me with this... I am reading an XML file created from the server and all is good except that when I try to process the file it's always skipping one of the first child elements. And when I run a test with no processing, just a straight reader and looping through the elements, the 1st element is there. But as soon as I add a check to see if the node is an Element, it skips an "Attachment" element.Here's my XML:

I have a form and initialize some global variables on its Load Event. There is a TextChanged event in one control (a textbox) that uses that value. The TextChanged event of the control is triggered before the Form's Load event even if I do not change anything on the TextBox, it looks like that happens when the control is loaded. Why is it doing it before the form? and what event can I trap in order to assure it's the first thing that happens?
Its as simple as this:
vb.net
Private Sub PackOutMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ActiveFlag = False
[Code]....
My guess is that the msgbox should not appear until the flag is set to true somewhere in the code and then change the contents of txtUser, but it is shown before the form.

I'm not really sure how to word it, if it is possible, but part of my program reads from a text file. It then pulls out the necessary information needed from that file by finding key identifiers. Right now the code is written to find the first key identifier and then read each line after that, locating each subsequent identifier and pulling the data from it. In a few cases, the format examples I've worked with are a bit different which results in a runtime error. How can I tell the program to essentially skip that part of the text file if it's not reading it right and continue moving on? Here is somewhat of an example of the text file.
DID/"DATA EXTRACTED HERE"
NAM/"DATA EXTRACTED HERE"
STR/"DATA EXTRACTED HERE"

I was having a problem with the debugger not stopping at breakpoints. After a lot of work that yielded no results, I realized that the problem was occuring in the form's load event and subs called from that event.
The problem is that it appears that the load event is not being called. Other startup forms in other projects in the solution seem to be working ok.
what could be keeping the the Load event from working?

I got a combobox, that when the texted is changed, its supposed to run a query to update a field in my database. Here is the issue The event im using is TextChanged, well unfortunately when the page loads, it changes the text when populating the values. Is there a way to make this event wait to fire until after the list is populated? Ive ran into this problem before with datetimepickers, but I was able to offset it with a boolean, but this combobox is calling the textchanged event everytime it adds an item to the list.

<Visual Studio 2008 / VB.NET /SQL 2008>. I have a form that populates data when Load event occurs. The problem is it looks like a slow motion movie when the form is loaded since there some quite amount data is populated. This is happen because I put a coding to populate data on Form Load event. Is there anyway that I can prevent the slowing down of form load event? I guess best thing is load form completely and trigger populating data.

I have VC++ windows service running on a windows 2008 server which invokes a VB.NET exe with certain comandline parameters using CreateProcess(). VB.NET application has a form wich uses WithEvents to handle certain event. These event handlers are set in the Forms Load event. Problem here is when i debug the VB.NET application individually the application works fine, Forms Load event is getting fired. But when the exe is invoked via the windows service the form Load event does not get fired. Note the Forms Show function called and not showdialogue.
Why this was done i am not sure it was a VB 6.0 code which i have converted to VB.NET. But everything works fine when i debug the application individually on windows 2008 64 bit.
