      Visio在VB6中的开发有很多现成的项目及代码，但在.NET领域相对比较滞后，但是从Visio SDK2007发布以来，给予Visio的C#开发逐渐多了起来，虽然和VB6的开发思路有一定的相似，不过平台不一样，做出来的东西差别还是有一定的距离，虽然总体慢一点，但是，DotNET框架的逐渐强大以及更多的DotNet程序和开发人员的加入，带给大家更高的整合价值以及更美好的发展未来。
    本人将会在C#领域将Visio的二次开发进行下去，希望大家一起学习研究，碰撞出更美的火花

Visio的几个重要对象

Application

Window （Application.ActiveWindow)

Document （Application.ActiveDocument)

Master、Shape

Visio XML格式文件分析
Master格式

Pages/Shapes格式

图纸的XML文档中，Master后面的Shapes集合中只有一个Shape对象
图纸的Shapes集合有多个对象，每个对象的NameU和Name值可能不一样，一般使用NameU

Visio基本操作的实现

VisApplication = this.ctrlDrawing.Document.Application;

VisWindow = VisApplication.ActiveWindow;

VisDocument = VisApplication.ActiveDocument;

//Settings

VisApplication.Settings.ShowShapeSearchPane = false; //显示搜索形状窗体

VisApplication.Settings.EnableAutoConnect = false; //自动链接（2007默认）

VisApplication.Settings.StencilBackgroundColor = 10070188; //vbGrayText

//文档各种显示

VisApplication.DoCmd((short)VisUICmds.visCmdViewRulers);

VisApplication.DoCmd((short)VisUICmds.visCmdViewGrid);

VisApplication.DoCmd((short)VisUICmds.ShowGuides);

VisApplication.DoCmd((short)VisUICmds.ShowConnectPoints);

VisApplication.DoCmd((short)VisUICmds.ShowPageBreaks);

//各种窗口

VisApplication.DoCmd((short)VisUICmds.visCmdShapesWindow);

VisApplication.DoCmd((short)VisUICmds.visCmdPanZoom);

VisApplication.DoCmd((short)VisUICmds.visCmdCustProp);

VisApplication.DoCmd((short)VisUICmds.visCmdSizePos);

SendKeys.Send("^(x)");

//VisApplication.DoCmd((short)VisUICmds.visCmdUFEditCut);

SendKeys.Send("{DELETE}");

//VisApplication.DoCmd((short)VisUICmds.visCmdUFEditClear);

SendKeys.Send("^+(p)");

//VisApplication.DoCmd(VisUICmds.visCmdFormatPainter);

SendKeys.Send("^(z)");

//VisApplication.DoCmd(VisUICmds.visCmdEditUndo);

调用工具条对象、菜单对象的方法
Application.CommandBars
Microsoft.Office.Core.CommandBars共享Office对象模型
使用CommandBar代替UIObject
CommandBar对象中，菜单及工具条是同一个东西
CommandBar、CommandBarButton、 CommandBarComboBox、CommandBarControl、和 CommandBarPopup

示例：执行视图中的工具条的所有按钮事件。

Microsoft.Office.Core.CommandBars commandBars;

commandBars = (Microsoft.Office.Core.CommandBars)VisApplication.CommandBars;

foreach (Microsoft.Office.Core.CommandBarControl control in commandBars["View"].Controls)

{

Microsoft.Office.Core.CommandBarButton button = control as Microsoft.Office.Core.CommandBarButton;

if (button != null)

{

button.Execute();

}

StringBuilder sb = new StringBuilder();

foreach (Microsoft.Office.Core.CommandBar bar in commandBars)

{

sb.Append(string.Format("CommandBar Name:{0}\r\n", bar.Name));

foreach(Microsoft.Office.Core.CommandBarControl control in bar.Controls)

{

Microsoft.Office.Core.CommandBarButton button = control as Microsoft.Office.Core.CommandBarButton;

if(button != null)

{

sb.Append(string.Format("Button Name:{0} \r\n", button.Caption));

}

Form2 frm = new Form2();

frm.txtContent.Text = sb.ToString();

frm.Show();

short flags = (short)VisOpenSaveArgs.visOpenDocked | (short)VisOpenSaveArgs.visOpenRO;

StencilOpenEx(wndVisio.Application, flags);

/// <summary>

/// 打开模具的公共方法

/// </summary>

/// <param name="visApp">按引用调用的VisioApplication对象</param>

/// <param name="flags">打开的模式</param>

private void StencilOpenEx(Application visApp, short flags)

{

List<string> stencilList = GetStencils();

string stencilFileName;

foreach(string stencil in stencilList)

{

stencilFileName = GetStencilsFileName(stencil);

if(!string.IsNullOrEmpty(stencilFileName))

{

visApp.Documents.OpenEx(Portal.gc.gStencileFileBasePath + stencilFileName, flags);

}

//关闭模具文件

visApp.Documents["Switch.vss"].Close();

visApp.Documents["Span.vss"].Close();

visApp.Documents["Line.vss"].Close();

visApp.Documents["Label.vss"].Close();

visApp.Documents["Construct.vss"].Close();

visApp.Documents["Monitor.vss"].Close();

Visio Shape的属性操作
StringToFormulaForString、FormulaStringToString函数
访问属性
设置属性
添加属性

//列出模具组

this.cmbStencilGroup.Items.Clear();

List<string> stencilGroups = stencil.GetStencils();

foreach (string group in stencilGroups)

{

this.cmbStencilGroup.Items.Add(group);

}

//根据模具组列出模具

string stencilName = stencil.GetStencilsFileName(this.cmbStencilGroup.Text);

this.cmbStencil.Items.Clear();

string tempName;

foreach (Master master in visApp.Documents[stencilName].Masters)

{

tempName = master.Name;

if (!stencil.IsExcludeItem(tempName))

{

this.cmbStencil.Items.Add(tempName);

}

//根据模具，获取对应的属性集合，遍历属性集合，列出属性名称

string stencilName = stencil.GetStencilsFileName(this.cmbStencilGroup.Text);

string masterName = this.cmbStencil.Text;

Visio.Shape shape = visApp.Documents[stencilName].Masters[masterName].Shapes[1];

if (shape != null)

{

List<StencilPropertyInfo> propInfos = property.GetPropertyCollection(shape);

foreach (StencilPropertyInfo info in propInfos)

{

this.cmbProperty.Items.Add(info.Name);

}

//根据模具、模具属性，列出对应的属性信息

string stencilName = stencil.GetStencilsFileName(this.cmbStencilGroup.Text);

string masterName = this.cmbStencil.Text;

Visio.Shape shape = visApp.Documents[stencilName].Masters[masterName].Shapes[1];

StencilPropertyInfo info = property.GetProperty(shape, this.cmbProperty.Text);

if (info != null)

{

this.txtName.Text = info.Name;//属性名称

this.txtValue.Text = info.Value;//属性值

this.txtFormat.Text = info.Format;//属性格式

this.txtSortKey.Text = info.Sort;//属性的排序

this.txtPrompt.Text = info.Prompt;//属性的提示信息

}

//根据模具，获取属性对象集合

public List<StencilPropertyInfo> GetPropertyCollection(Visio.Shape shape)

{

List<StencilPropertyInfo> list = new List<StencilPropertyInfo>();

StencilPropertyInfo propertyInfo;

Visio.Cell shapeCell;

short shortSectionProp = (short)VisSectionIndices.visSectionProp;

if (shape != null)

{

for (short i = 0; i < shape.get_RowCount(shortSectionProp) - 1; i++ )

{

if (shape.get_CellsSRCExists(shortSectionProp, i, (short)VisCellIndices.visCustPropsLabel, 0) != 0)

{

propertyInfo = new StencilPropertyInfo();

shapeCell = shape.get_CellsSRC(shortSectionProp, i, (short)VisCellIndices.visCustPropsLabel);

propertyInfo.Name = VisioUtility.FormulaStringToString(shapeCell.RowNameU);

shapeCell = shape.get_CellsSRC(shortSectionProp, i, (short)VisCellIndices.visCustPropsPrompt);

propertyInfo.Prompt = VisioUtility.FormulaStringToString(shapeCell.FormulaU);

shapeCell = shape.get_CellsSRC(shortSectionProp, i, (short)VisCellIndices.visCustPropsFormat);

propertyInfo.Format = VisioUtility.FormulaStringToString(shapeCell.FormulaU);

shapeCell = shape.get_CellsSRC(shortSectionProp, i, (short)VisCellIndices.visCustPropsValue);

propertyInfo.Sort = VisioUtility.FormulaStringToString(shapeCell.FormulaU);

//shapeCell = shape.get_CellsSRC(shortSectionProp, i, (short)VisCellIndices.visCustPropsType);

//propertyInfo.PropType = VisioUtility.FormulaStringToString(shapeCell.FormulaU);

//shapeCell = shape.get_CellsSRC(shortSectionProp, i, (short)VisCellIndices.visCustPropsInvis);

//propertyInfo.InVisible = VisioUtility.FormulaStringToString(shapeCell.FormulaU);

list.Add(propertyInfo);

}

return list;
