View 8 RepliesWhy Does Form Crash When Change Custom Control
Jun 11, 2009I have created a custom control that is included in a control library that is referenced by a VB Forms application.
When I modify the control, and have the application open in a VS window, VS usually asks me if I want to reload items that have changed.
However, a couple of times, it has not asked me this, and when I go to open the form that contains the modified control, I get an error window warning me that if I ignore the error message and continue, then I risk making VS unstable. I've learned to ignore this error message, continue, and immediately save the form to a new file.

View 1 RepliesChange The Three Dots (ellipses) (...) To Custom Characters In DataGridView When Cell Content Is Truncated?
Dec 15, 2010In DGV, if the contents of the cell is truncated, the DGV shows ellipses (three dots) (...); but as the font is set to a Gujarati font, it displays a Gujarati alphabet "ઈઈઈ" instead of "..." because the Gujarati character "ઈ" is coded with the English "." (dot) character.In Gujarati font, "." can be generated with the English character "P".So, How can I change the ellipses to English "P" character? OR How can I remove the ellipses completely?I have found a similar solution by berc on Tuesday, August 31, 2010 1:33 PM :but I am not sure it is the perfect and/or the only way to do so, AND it will really work or not
View 2 RepliesVS 2005 What Can Use Instead Of A Pointer
May 1, 2010I understand there are no pointers in VB.Net. I need to use something similar.The issue is that I have a structure that represent a deck of cards, with elements showing how many of each type of card there is. So I have my_deck.ace, my_deck.two, and so on.What I want to do is set a pointer called current_element that refers to any element in the structure. It may one time point to my_deck.three, and another time to my_deck.nine, and so on. It could point to any element.What I want to do is, for instance to set current_element to point to my_deck.ace, then decrementing current_element would reduce the count of aces by one.[code]that would work, but it's inelegant, I have about 30 different operations to perform, some of them using several lines of code. I'd like to avoid this if at all possible. I could tolerate doing it 2 or 3 times, but not 30.

View 12 RepliesCompiled C Dll Can't Set Pointer When Called From ASP.NET App?
Dec 10, 2009I've got a 3rd party C application that's compiled to a non-.NET non-COM DLL. It has one simple function declared like so: Declare Function CapiTaxRoutine Lib "taxcommono.dll" (ByVal sInData As String, ByVal OutputData As String, ByVal intINPutLength As Long) As Integer
If I place the taxcommono.dll in my path (C:WindowsSystem32 is what I'm using because it's what the vendor recommends),I can wire up a call to the function and it works just fine.It returns a 1 or 0 for success/failure, but it also sets the value of the OutputData string parameter (using some C pointer magic I'm not familiar with) to a huge fixed width format return record that has the data I need.When I call it from a .NET .exe application, it works just fine.When I try to call it from an ASP.NET application via a referenced compiled .NET wrapper DLL, it runs but can't set that string.In order to get it to run, I can't have taxcommono.dll in my path, but rather have to place it in my Bin directory of the web project.Does anyone know of a reason it can set the pointer when called from an .exe application but not when called from a web app?The .NET wrapper DLL I'm using works when called from our ERP software, which is not web based. But when I add a reference to that same DLL in the web app, it won't give me that output value.am used to just getting a return value instead of a function setting the value of one of my input parameters.

Pointer - Rewrite A C++ Library
Jan 4, 2012I'm trying to rewrite a C++ library. But I have an issue. I'm not extremely pointer-savvy. In the C++ class there is a std::vector that holds unsigned int pointers (vector<unsigned int*>), and the int pointer just points to an array of integer data.
Here is the C++ code I'm a bit unsure about:
unsigned int* relocation = m_relocations.front();
m_relocations.pop();
unsigned int* reloc = *(unsigned int **)relocation;

Using Pointer To Type In Dictionary Value?
Feb 23, 2011This small snippet of code is to increment a count value (integer) which is stored in a dictionary using my referenced object as a key. When the dictionary is small, multiple lookups aren't a big deal but this particular dictionary can get quite large.
Private RefCount As IDictionary(Of ILifeTimeManaged, Integer)
......... CODE HERE.....
Private Sub IncrementRefCount(ByVal entity As ILifeTimeManaged)
Dim prevCount As Integer
''# if we have no reference entry, add one and set its count to 1
[Code] .....
I find a corresponding dictionary entry then increment the int stored in the value, or add a new dictionary entry. Is it a bad idea to use a pointer to the dictionary value? Then I can avoid the second key lookup when I already have gotten the value. How would you implement it? Is this even possible in .NET4? Can I do it using IntPtr do you think? [URL]
RefCount.Item(entity) = prevCount + 1
