• xlordt Process not completing

  I have a vb form that runs a command line executable that creates a diff file from two existing files. When I run the program from the command line it creates a 419Mb diff file. When I run it as a process from my VB program it gets to ~400 Mb and stops. If I kill the VB program the command line executable continues to run and finishes the diff file. So I have 2 questions. Why does the process stop before for it finishes when I run it inside vb Why does the program continue to run when I kill the VB app. Here is my code Private Sub xdelta( ByVal strFile1, ByVal strFile2, ByVal strDelta) Dim strError As String Dim p As New Process Dim info As New ProcessStartInfo info.UseShellExecute = False ...Show All

• Keith Seifert ToolTip control and DataGridView

  I have a tooltip control on my form. The tool tip pops up great for all the other controls on the form except for the DataGridView control. Any idea what could be the problem Sorry, I should have told you before, I did try that option. Does not work. Precisely. I set all properties at Design time. The tooltip shows for all the other controls except for this grid. Not sure if it matters, The grid is "DataBound" , and it is placed on a panel. Well, it works fine for me... So you've added a tooltip control to your form (lets say "ToolTip1"). And then you set the dynamic property on the datagridview: DataGridView1.ToolTip on ToolTip1 = "some text" And then you set DataGridView1.ShowC ...Show All

• hawash Question about how to close whole program

  Hey guys i have another stupid question 2 ask, apologise for my ignorace once again as this myt seem like a really stupid question. I have multiple forms for my program.

• Paul Verdu Validate textstring as DateTime

  Hello , Can this be done in VB2005Xpress Form elements: one TextBox, one Label (TextBox is used to receive Birthdate input, Label displays "<1", "1" "the age which is calculated from Today's Date - Birthdate" or " "). The age formula and the If statement for "<1", "1", "age" and " " is done. Here the TextBox is the choice for Birthdate entry. It is the most cost effective. DatePicker is excellent choosing a future date where the user want to be sure that the Day picked out do not fall for example on Sunday.

• Namrata_Gupta Threading Race

  I've got a multithreaded app that I'm working on. The code below is the shell of it. "DoABunchOfWork" is a function that needs to go out and get info from any number of SOAP webservices(this code is stripped for simplicity). I need to create an instance of an object that actually does the communication and run a method on the object. That code is easy as well. The problem that I'm having is with making each of those methods execute asynchronously. I have a race condition where it appears that System.Threading.WaitHandle.WaitAll() is returning before all of the callback finish, thus causing my return value to skew. Anyone lend a hand as to how modify this code so that I don't have that issue. Public Class ActionLayer Private De ...Show All

• bikerchick #IF Designer Type Preprocessoring?

  I was told to come here and ask this. I'm making an application that has a couple panels and I always run into the problem of where to design all the panels. I hate to resize the boxs all the time to make changes to them and usually work on them outside of the forms main size. Question: Is it possible to do something like this. #If Designer Then Me.ClientSize = New System.Drawing.Size(1200, 1000) #Else Me.ClientSize = New System.Drawing.Size(600, 460) #End If 'This is also used to move panels and such around... my expample resizes the actual form. I mostly want to do this to the panels because i've found that resizing all my panels onload causes a long lag on slower computers when starting up (its the only thing im calling onLoad the res ...Show All

• Baldwintm Poor Forethought

  I have run into a problem which I should have foreseen. My program lists Part records and their S/N's On my form I have listbox1 which is bound to an Access dB and is filled with S/N's for a given Part number. Listbox2 is unbound and is populated with items from listbox1 so that I can manipulate the list. Now that the list is manipulated to contain what I want I need to get this list of S/N's back to the dB. My problem is I can't get the items from Listbox2 back to Listbox1 because Listbox1 is Bound to the dataset. does anyone have any thoughts as to how I would go about this thanks tattoo I think the problem with that solution is, If I have changed any of the existin ...Show All

• Anton__ "TrollKit 1.0" - Not quite "Patterns & Practice" Material

  I am sure the "Patterns & Practice" team @ MS are squirming about this InteropForms Toolkit 1.0. Honestly, I am a little disappointed in the emergence of this toolkit. Ideally MS should’ve created a migration path process and set of patterns to allow the developer to understand the inners-workings of this Frankenstein type applications. Instead MS decided to give the developer community what I would call a “TrollKit”. What happened to teaching people how to fish, instead of providing them with fishes Please do not use this “Trollkit”, instead take the route of visual inheritance & COM Interop, create your own set of class libraries, add WinForms to these class libraries, and you will be able to do anything with t ...Show All

• Whoisit How to get hold of the linenumber of the line where an error occurred

  Hi. I have tried ( in vain ), when executing the VB executable, to find out how to show the line number of the error that occurs. I can access the line number when I'm in the VB IDE environment, but not when I run the executable. Below is the code I use to access the line number ( I also tried lo_stacktrace.ToString(), but again the line number did not show when I ran the executable ) This leads me to the question: Is it at all possible to access the line number when the executable is run Private Function CodeRef( ByVal po_ModInfo As t_ModInfo _ , ByVal po_ex As Exception _ , ByVal pb_ReturnSource As Boolean _ , ByVal pl_FrameNo As Long _ ) As String Dim lo_stackframe As Stac ...Show All
